San Francisco style sourdough bread

SF Sourdough: Time, Patience and Planning Skills!

His recipe intrigued me when I first read it; the use of the refrigerator, the promised taste and sourness, and the sheer amount of steps and time. These kind of recipes always trigger my interest. Plan ahead for this recipe because it is going to take 4 days from start to finish. Perfect to incorporate in a very long weekend of baking. This recipe is based on the San Francisco Sourdough recipe from Peter Reinhart’s latest book ‘Artisan breads every day’. But of course, as you may know by now, I have made my own version (which comes with exact measurements and a time table!).

The trick of this recipe is to fit it in with other activities like sleep and work. The times given in the time table at the bottom of the recipe keep this in mind. Of course you can be a bit flexible with the time table, especially with the 34 and 15 hour periods the dough spends in the fridge. But alterations can have an effect on taste and texture. For example if you extent the time in the fridge the bread will become more sour, but the gluten strength will weaken, so you probably get a flatter, denser bread. If you want to make more than one loaf, just double or triple or quadruple the ingredients. We usually make 6 breads in one batch. That’s the maximum our spiral mixer can handle.

For the starter in this recipe I use a sourdough culture which is made with 100% whole grain rye flour. A sourdough culture based on rye flour is easier to maintain, it does not transform into a slurry when you forget about it, it is easier to stir because it has almost no gluten and it smells very very nice, a bit like fruit. I maintain the starter as a ‘almost’ stiff starter. This way it stirs easy but does not add as much water to the dough as a poolish starter. It is also very forgiving in the amount you feed it. As I am a bit lazy in feeding, normally I only feed it once a week, after my weekend baking. I just give it a few table spoons of water and rye flour, stir, and ready!

Ingredients for the Starter

126 g bread flour

83 g water

24 g sourdough culture

Making the Starter

In a bowl stir together 126 grams of bread flour with 83 grams of water at room temperature with 24 grams of the (rye) sourdough culture. Mix it well for about 1 minute until all the ingredients have been combined and you have a dough like ball. It is not a problem if your dough still looks a bit rough. Cover the bowl with clingfilm and let it preferment. After a minimum of 9 hours at room temperature it is ready for…the fridge. It will stay there for the next 34 hours! This means that on the morning of day 2 you put it in the fridge and in the late afternoon of day 3 you take it out again (see time table at bottom of recipe).

Ingredients for the SF Style Sourdough

makes 1 loaf (65,2% hydration)

Starter (233 g total weight)

264 g bread flour

50 g spelt flour (pref. whole grain)

204 g water

9 g salt

Making the Loaf

So, it is now probably somewhere in the afternoon on day 3 of the recipe (17.00 h if you stick to my time table). Take the starter out of the fridge and immediately start making the dough. Combine the starter with the 204 g water and stir for 1 minute to loosen the stiff starter. Add the flour and salt and knead (we use a spiral mixer) for 3 minutes. Cover the mixer bowl and leave to rest for 15 minutes.

Take the dough out of the mixer bowl and onto a floured work surface and do one stretch and fold (a full letter fold, left over right, right over left, bottom over top, top over bottom; see our bread movie to observe this technique if you are not familiar with it). Leave covered to rest for 15 minutes on your bench. Do a second stretch and fold. Return to the (greased) bowl, cover and leave to rest for 40 minutes at room temperature. Now put the dough in your fridge and leave it there for the next 15 hours (yes you can go to sleep, the yeast cells in your dough probably will do a bit of hibernating of their own in the fridge, the bacteria stay more active in this colder climate and tend to produce acetic acid, which, if all goes well, will give your bread the sour taste of the sourdough.

It is now day 4 of the SF sourdough making process: Baking Day! In my time table it’s now 10.00 in the morning.
Take the dough out of the fridge and let it acclimatise for 2 hours at room temperature.

Now it’s time to shape. You can make a batard/oval loaf or a round one. I like to use the batard shape for this bread, it’s also good for a more even bake. I also use floured proving baskets/bannetons. Transfer the shaped dough in a proofing basket or baking pan, dust a bit with flour, cover and leave to proof for 2,5 – 3 hours (at room temperature which is about 21 ºC). When you think it has risen enough, use your finger to carefully make a very small dent in the dough. If the dent remains, the bread is ready to bake, if the indentation disappears, the dough needs a little bit more time.

Preheat your oven to 235 ºC / 455 ºF (at what stage you preheat your oven depends on how long it takes for your oven to heat through, some take 30 minutes, some, like ours, with stone floors take a lot longer, up to two hours. The preparation time from this point until the bread actually goes into the oven is 3 hours.

Now your loaf is ready for the oven. Slash the top of the loaf with a lame or bread scoring knife. To get a nice crust, try to create some steam in your oven by putting a small metal baking tray on your oven floor when you preheat the oven and pouring a half cup of hot water immediately after putting the bread in the oven. Release some steam by setting your oven door ajar (perhaps with the help of a wooden spoon or oven mitt) 5 minutes before the bread is ready. If you are going to create steam with a baking tray, you maybe also want to turn your oven temperature a bit higher, because you are going to lose some heat in the process.

After 45 minutes of baking your loaf should be ready. Transfer onto a rack and leave to cool. This loaf also keeps very well in the freezer. But please make sure to eat at least some of it while fresh!

Note: We use European flour which absorbs a few % less water than American type flour. People using this type of flour should add 3-8 ml water to the final dough. If you dare you actually make the dough a few percentages wetter to get bigger ‘holes’ in your crumb. I lowered the amount of water in this recipe to make the dough easier to handle.

    I made this recipe for the first time this week. As a new person to sourdough, it’s the best recipe I’ve used yet. Wonderful!

  2. Vale says:

    Thank you for your inspiring recipes!

    I have a question concerning the water temperature when making the loaf. As the starter comes straight out of the fridge, should I take into account the fact that it is going to be about 6 degrees Celsius when calculating the water temperature for the dough? Should I make the water hotter?

    • Weekend Bakers says:

      Hi Vale, try to aim for a dough temperature of around 25C to 27C. So you need water of about 30C to 35C counteract the fridge. Happy baking!

  3. sue e says:

    Words can’t describe how delighted I was with this recipe: my loaf texture was tasty, spongy and perfectly chewy with a lovely crisp crust from my new banneton. Well worth the 4 days planning! Hubby is well pleased.
    I have to say that the recipes on this website are so successful and practical to fit into a normal workaday. I have bought one of the books referred to in some of the articles here, but can see how the modifications by ‘weekend bakers’ are well worth their effort. Well done you two – you’re a favourite on my task bar.
    Sue e

    • Weekend Bakers says:

      Thank you so much Sue. We are so pleased you value our efforts. Hope we can inspire you some more in the future.

      Happy baking and lots of loaves!

  4. Ludovic leclerc says:

    Baked the loaf today, quite happy with the result. Next one planned for Monday. Family liked it.

    • Weekend Bakers says:

      Great to hear! You can play around with the recipe a little bit of course as you are pleased with the results you could try and make a next version with a slightly higher hydration percentage.

  5. Ludovic leclerc says:

    Hi good morning to you. It is the day of the baking and i am looking forward to see the loaf coming out of the oven. You mentioned having lowered the water content in this receipe to make the dough easier to handle for us home bakers. Could you please let me know what would be otherwise the quantity of water you use and what percentage hydration it would then be. Many thanks. Have a good eeekend.

    • Weekend Bakers says:

      Hello Ludo,
      We are not exactly sure anymore, because we recalculated everything and changed more things from the original recipe but is was around 5% more or close to 300 g water in total, divided over starter and final dough probably.

  6. Susan says:

    I made this bread today, for the first time, and it turned out simply delicious. Just the right tinge of sourness.
    I have never made SD bread before, so it must be sheer luck! Will try again just to make sure that I have got it right.
    The dough was very very soft when I poured it into the Dutch oven. I never thought for a moment that it would rise.
    I was all ready to bin it.
    Is the dough meant to be so soft, almost like thick cream???
    But it rose tall and proud?
    Thank you for sharing your wonderful recipe.
    I also made the walnut, fig and prune bread and it also get out like a dream. Perfect in every way.

    • Weekend Bakers says:

      You are really on a roll Susan. It all sounds excellent!
      Keep up the good baking. And now you have also experienced the excellent workings of the Dutch oven.

  7. Mirjam says:

    A great recipe. One small question. Do you fold before the shaping?

  8. Magda says:

    Fantastic recipe, only bread I am going to bake now, per request of my family.
    Used rye flour instead of spelt. Very good result.
    THANK YOU!!!

  9. Bernie the banjopicker says:

    I love the sourness of this one! I’ve also got some great oven spring with this – it flattens worryingly when flipped onto the peel and slashed, leading me to think I’ve over proofed it. But it bounces right back. Lovely. One thing I’m not too fond of is the taste of spelt. If I were to substitute plain wholemeal, or just more white flour instead of the spelt, would you adjust the hydration? If so, by how much?
    – Bernie

    • Weekend Bakers says:

      Hello Bernie,
      When using wholemeal we would leave the hydration as is, when using white flour we would adjust it probably to a few % less and see how the dough comes together.

      Good luck with it and happy baking!

  10. kaisman says:

    just did this bread and it was awesome- the crust’ the crumb, the flavor – EVERYTHING.
    i just made this bread 75% hydration by adding 40g water to the final dough.
    thank you

  11. Adrien says:

    Thank you for this great recipe !

    I have a question about the optimal fridge temperature. I measured 10 °C on the top and 3°C on the floor of my fridge and I was wondering what is the best temperature to let the dough proof during the night ?

    • Weekend Bakers says:

      Hi, our fridge is around 6C, but anything under 12C is ok, because the yeast will become dormant at this temperature.

  12. antonella ferrante says:

    scusate se scrivo in italiano, vorrei chiedere perchè così tanto starter 233g per 314g farina?grazie ciao

  13. Teresa Teague says:

    Thank you so much for sharing your recipes.
    Your explanation and instructions for sour dough starter were very helpful. I made the starter according to your instructions and my bread turned out perfect. Rye flour makes all the difference. (I used Hodgson Mill stone ground whole rye flour). The flavor profile has gotten even better with the 3rd loaf and my starter smells wonderfully pungent.
    It’s amazing that no commercial yeast is needed and the bread rises perfectly.
    I had tried the seed culture starter recipe in the Bread Baker’s Apprentice which was less than mediocre and I think it’s because it begins with rye flour but is fed only bread flour thereafter.
    So thank you, thank you….finally a loaf of sour dough bread that actually tastes like sour dough.

  14. David Castro says:

    Hi! I recently made this bread and it turned out a bit sweet? I’m not sure if it’s because I converted the grams to ounces or my sourdough culture is acting weird. I suppose I should mention that I used Dark whole wheat rye flour (if it matters?). But either way the crust was nice and this was a good experience for my first bread!

  15. Dylan Schink says:

    This has been my weekly loaf for a couple months now and I’m incredibly happy with it, though I’ve found I get best results baking at 200˚ on a granite stone for 40 minutes. What advantages does doing the falling temperature thing have over just baking at 200?

    Another question: I of course slash my loaf before I put it in, but I never get that nice ear, I just get a more stretched out glossy patch of crust than on the rest of the loaf. How do I slash for that beautiful torn look?

    • Weekend Bakers says:

      Hi Dylan, most bakers do not use a falling temperature. It is a simulation of ‘old’ wood fire oven. You fire-up the oven with wood, remove all the burned out residue and put in the bread. This way the oven starts at about 240 and falls to 180. Our Rofco does the same by switching off the heating elements, the heat retention of the stones will bake the bread. Most bakers with deck ovens do not use this procedure because switching on and off the oven takes too much time, energy and steps. So find out what works best with your oven, perhaps you can heat your oven to 230, put in your bread and after 10 minutes turn down the oven to 180. The high starting temperature will kick the bread in its b*tt and will perhaps improve your ear on the bread. Also steam is crucial during the first 10 minutes for getting a glossy crust with a nice ear. Happy baking!

  16. Martin says:

    A lot of SF sourdough recipes use about 200-250g of recent-fed sourdough culture (depending upon hydration) as the starter instead of building a levain as you have. Is there a reason why you use so little culture (24g)? Is it all about taste or is it, in effect, the same end result just done a little different?

    • Weekend Bakers says:

      Most recipes make you keep about 300g of culture day in day out, week in week out, when you do not bake regularly you need to throw away a lot of starter (and flour) during refreshing your culture. By keeping a small amount of culture and making / building a poolish or starter out it you are more flexible and do not to keep as much culture. All resulting in more flexibility and less waste.

  17. Shoshy says:

    Hello, thank you for the lovely site, very helpfull tips!
    Is it possible to keep the ready dough (before shaping) in the fridge for 24 hours instead of 15?

    • Weekend Bakers says:

      Hi Shoshy, changing the time from 15 to 24 hours should be no problem, however over time the quality of the gluten and the strength of the dough will degrade. So there is an end to amount of time a dough can stay in the fridge. We never tried it, but it should not give real problems. Happy baking!

    • Teresa Teague says:

      I did 24 hours with excellent results. Having a little flexibility with the time helps to work around one’s schedule.

  18. erin says:

    this is beautiful bread. Even a novice can follow these excellent directions and create wonderful bread. Thank you for rescuing my deteriorating sour dough experiences…now my sour dough breads are awesome :-)

  19. new_baker says:

    Lovely website! When you use your proofing baskets, do you line them with a cotton cloth, or does the dough go directly in there without any lining ?

    • Weekend Bakers says:

      Hello, we do not line the proofing baskets. We simply dust them lightly with some flour before putting in the dough. Happy baking!

  20. Ishi butcher says:

    I like your website…useful information. I am trying the SF style sourdough bread,
    but if I want to produce two loaves, do i double the starter and the Ingredients or
    do i use the same 233 g starter and double the rest of ingredients ??

    • Weekend Bakers says:

      Hello Ishi, for two loaves you need to double everything, so you need 466 g of starter. Happy baking!

  21. jill says:

    I had a go at this bread at the weekend and I had a few issues.

    Firstly the oven temperature seemed way too hot – my bread was baked with 18 mins to spare. I adjusted it down slightly, to 220C, as I have a fan assisted oven but not sure whether I should have reduced it more. I am off to buy an oven thermometer at lunch so I can check the actual temperature.

    Secondly the bread was not sour enough for my tastes – I am assuming this was due to the maturity of my starter (just over a week old at time of baking).

    I am going to have another go this weekend as the process was easy to follow – thanks for the timings it made it so much easier :) Although it baked too fast the texture inside was spot on and it tasted good too!

    • Weekend Bakers says:

      When using fan assisted ovens, you need to lower the temperature at least by 20C. It is also a good thing to turn the oven down to for example 150C when the bread has the right color. This will stop the browning process but the temperature if still high enough to get a full bake. Happy baking!

  22. David O. says:

    After probably 10 attempts, I was very satisfied to finally produce two loaves this weekend that actually resemble the image in your recipe. There are lots of holes and the taste and texture is wonderful! The key thing I have learn’t is that it’s crucial to refresh the starter the day before using it, and also to use plenty of coarse flour – I used wholegrain flour- while shaping the dough for the banneton to prevent any sticking.

    I have a 40C dough proving function on my oven, and have found that if you get the above right, you can bring up to room temperature AND prove in the banneton in less than 2 hours. While the dough will not quite double, I’ve found the ‘ovenspring’ effect when the loaves are put in the hot oven compensates for this, more than doubling the size compared to the dough that left the fridge.

    • Weekend Bakers says:

      Hi David, there is balance between a full proofing, a bit underproofing and oven spring. Slighty underproofed gives indeed a nice oven spring. Controlling the temperature of your dough gives access to consistency in proofing times. We have thermometers lying around everywhere to measure everything! 😉 Happy baking!

  23. Liz Wilson says:

    Is it OK to leave my starter in the fridge for an extra 24 hours….something has come up that will prevent me from being at home for Day 4…..Thanks

    • Weekend Bakers says:

      Yes Liz, we think it can be OK, but there is a chance the gluten will get weaker as time progresses.
      Good luck with it!

      • Liz Wilson says:

        It was a little flat…but totally delicious…lovely chewy tasty texture. Another one due in the oven tomorrow (and staying to the timetable…. ) Will report back.

        Thank you lovely weekend bakery

    Hello, i found your blog very useful, and the process its quite simple comparing others i have read, for the moment i dont have any spelt flour, can i replace it with more bread flour?, thank you!

      Yes, you can Laura, no problem. You can use bread flour or whole wheat flour if you happen to have that.

      Happy Tartine baking!

  26. cookandbaker says:

    Stunning loaves! And the crumb looks so aerated and elastic! Is there a link to the ‘sourdough culture’ itself?

    Best wishes,


  27. Petra says:

    Hi there,
    I followed the recepe to the letter , so far.
    I am on a differend time table, so it is my Day * Evening * of day 3.
    I did the water with the starter stiring for 1 Minute, added the flower and the salt, kneaded it in my Mashine for 3 Minutes BUT, that dough is soooo stiff * I added a little bit more water and kneaded by hand for 1 minute * but it is still very still.
    It is now at the first 15 minute rest and I have no Idea how to do the letter fold stretch with such a stiff dough?

    I really followed your instructions.

    I always assumed that it is called SanFrancisco Sourdough when it is made with the specific Starter that you only get in SanFrancisco or purchase and not the Method of making it.
    Am I wrong?

    • Weekend Bakers says:

      Hi Petra,
      This bread is of a reasonable high hydration and as you can see in the picture the dough is not / should not be stiff. What flour did you use?
      The discussion about sourdough culture is a difficult one. You can get the culture from SF, but as soon as you feed it with local flour, will it still be the same? People have all kinds of opinions about this and somebody has to do some scientific research to clear this up. Our own findings with different cultures we used point in the direction of local taking over when feeding with local flour. But the SF is as much about the method as it is about the culture. Because we used our own culture we called it ‘SF style’.

      • Petra says:

        I used strong Breadflour and spelt flour, it is so stiff that I had to pull real hard to get the fold and stretch done.
        I used the same amount of Starter, Flour , Water and Salt as in the recepe.
        I must have done something wrong if it is not working for me.

        So I shall see what happens when it is time for it to come out of the fridge for the last steps.

        Thank you so much for the explanation reg. the SanFrancisco Sourdough Bread e.g Starter.:)

        It makes sense that once it is Europe or anywhere else in the World it will feed on differend yeast in the Air.

        • Weekend Bakers says:

          It all sounds really OK, except for the dough not cooperating of course… Just in case: Please note that spelt flour does absorb more water than wheat flour so if you maybe used a different combination of both (more spelt), this could already account for a different result. But it is really hard to judge for us, without seeing of course. The pictures give the best indication of how the dough should look.

  28. Francesca says:

    Is it possible to scale up the recipe by doubling all the amounts?

    • Weekend Bakers says:

      Hi Francesca,
      Yes of course, you can double, triple, quadruple as much as you like. As long as you divide the dough by 2, 3 or 4 et cetera to make individual loaves again, you can also stick to the baking times given in the recipe. If you would double up to make one big loaf, you would have to adjust the baking times.

      Good luck with it,


  29. jim says:

    what make is your oven with orange spray bottle ?

  30. Carina says:

    Hi what is the possibility to bake this bread with 100% rye flour? Will it work and will the end product be hard or soft?

    • Weekend Bakers says:

      Hello Carina,
      You cannot just substitute wheat with rye flour, the result will be completely different. The most important difference is the amount of gluten / protein. Rye has a very low protein content, so a 100% rye loaf has a much denser crumb and handling the dough will feel more like working with clay. You can check out some of our recipes for rye bread in our best bread recipe section:…d-recipes/

      Happy baking!

  31. Rachael says:

    I love your blog!!!
    Have you ever used any starters from a company called Sourdough’s International?
    I keep hearing about them but I want some reviews from some fellow bakers.. If anyone knows, let me know! Thanks : )

    • Weekend Bakers says:

      Thank you so much Rachel. We have never ordered sourdough from this company. It is all very interesting these different cultures and how it all works. We have done some initial experimenting and we need to do more to draw some more definite conclusions but very carefully we must say that when you get a culture from the other side of the globe but you feed it with your own local flour, chances are you will end up with a local culture again. We tested this with another baker by exchanging cultures and this is what happened. But like I said, more testing needs to be done and probably a scientist needs to be involved to explain and analyze what exactly is happening during this process.

      Any other bakers with experience with the company or the subject? Would be very interesting to hear!

      Happy Baking!

  32. Sandra says:

    I baked this over the weekend and the bread tastes too sour. What causes this and how to prevent this from happening in the future?
    Thank you.

    • Weekend Bakers says:

      Dear Sandra,
      This recipe, with its long fermentation in a cold environment is created to develop sour taste. But the results for sourness between people who bake this bread still vary a lot also depending on the workings of their culture. For some people it is the highest goal to get more sourness in their bread. This recipe with its 4 day process gives the acidic acid a good chance to develop. Acetic acid, or vinegar, is the acid that gives sourdough much of its tang.
      The best thing you can do is try a recipe with shorter fermentation times and proofing in a warmer environment like our pain naturel or the Tartine style bread.
      Another tip is to maintain your starter at a higher hydration level. Lactic acid-producing organisms seem to thrive in a wet environment whereas acetic acid is produced more abundantly in a drier environment.

      Good luck with it and happy baking!

      Marieke & Ed

  33. Abel says:

    One question, refered to the baking process.
    The temperature you suggest to bake it’s 235C during 45 minutes. Is that ok?
    About the steam. Do you recommend steam during all the baking process or just in the first minutes? I’ve seen some recipes in which you create steam during 10 minutes and then you remove the tray with hot water. Thank you very much.

    Abel, BCN.

    • Weekend Bakers says:

      Hello Abel,
      Yes the temperature and time are OK, but you should always check the temperature of your own oven to know that it really has this temperature too (some ovens have big deviations). Also see our tips about getting to know your oven:…your-oven/
      Steam does its job in the first minutes of baking, keeping the skin of the dough soft so the bread can expand (oven spring) after this you can let the steam escape if you want a nice crusty loaf (opening the oven and getting the tray out would maybe be not such a good idea because you will also loose a lot of heat (with a normal household oven that is). So it is better to use the right amount of water that will vaporize during baking and to let the excess steam escape by a small opening. If you are aiming for soft bread (rolls for example) then you don’t have to let the steam escape.

      Happy Baking,

      Ed & Marieke

  34. Raluca says:

    Thank you! will do that!
    I did see it and will try soon!

    have a nice evening!

  35. Raluca says:


    and apologies if this question was asked before.
    I have just started making this with your rye sourdough culture and the lovely Dutch flour and can’t wait to see the results.
    just a quick question: can I extend the first fermentation period from 9 hrs to maybe 12 or will this ruin everything?

    thank you!

    • Weekend Bakers says:

      Hi Raluca,
      That should be no problem, just make sure to put it in a slightly cooler place if possible, not the warmest space in the house.

      Hope it will turn out great!

      PS: Have you seen, I posted the no knead version of the brioche? You can find it here:…d-version/

  36. Winter says:

    Hi Ed and Marieke,

    What a wonderful and fairly easy recipe. I tried it this last weekend and I couldn’t believe how perfectly chewy the inside was, how crispy the crust was, and how it was the perfect sour flavor! Thank you! Here’s a pic:

    I only had one issue–my bread didn’t have very many bubbles like you have in your picture. I stuck to the timeline given and when I pulled it out, it looked like it rose beautifully and that there would be plenty of bubbles, but alas, there were very few when I cut it open. So I’m wondering if you have any recommendations on getting more bubbles. Any recommendations for baking at altitude? I live in Utah–about 3500 feet above sea level.

      Hello Winter,
      The bread looks wonderful! Thanks for sharing the picture with us.
      About the bubbles: they are a result of using wet dough (high hydration) and careful and not too much handling of the dough. If, and I am assuming you do because you live in the States, you use American flour you should also compensate by using a bit more water in the recipe. Maybe you have seen this in the recipe above:
      ” Note: We use European flour which absorbs a few % less water than American type flour. People using this type of flour should add 3-8 ml water to the final dough. If you dare you actually make the dough a few percentages wetter to get bigger ‘holes’ in your crumb.”
      This also means that, although the dough is wet it is important not to (deliberately or not) compensate by using greater amounts of flour while handling and shaping the dough. You can also try to keep the handling of the dough to a minimum, do not pull and press et cetera, but shape and transfer the dough with decisive but light movements.

      Hope this helps you getting your bread even more perfect!

      Happy Baking,


      • Winter says:

        Hi Marieke,

        Thank you for the quick reply. Yes, I live in the states. I will try a little bit more water this next time and try to be a bit more gentle when handling the dough. I am excited to try again and I’ll let you know how it goes.

        Thank you again!

    Hallo Caroline,
    Leuk van je te horen. Jazeker, geen enkel probleem om die 50 gram te vervangen met whole wheat of rye, dat maakt geen verschil, behalve een beetje in smaak.
    Ik zou nog willen zeggen wees in het begin een beetje genereus met het inbloemen van je mandje en sprenkel ook wat op je brood voordat je het omkeert en in je mandje legt. Je zult zien dat het steeds makkelijker gaat en dan neem je wat gas terug wat bloem betreft. Het rijzen in de oven is belangrijk maar tegelijk ook een lastig onderwerp omdat het met veel aspecten te maken kan hebben. Ten eerste moet je brood voordat het de oven in gaat tot het optimale punt gerezen zijn (de rijstijden bij onze recepten gaan uit van een deegtemperatuur van 24 Celsius, als je deeg kouder is, dan duurt het uiteraard lager). Dan moet je oven goed op temperatuur zijn en niet te veel in temperatuur zakken zodra je de deur open doet. Voor oven-rijs is het met name belangrijk dat de buitenkant van je brood de eerste minuten zacht blijft in de oven. Daarom gebruik je stoom want anders lukt dat heel moeilijk. Stoom zorgt ervoor dat je brood nog zacht blijft en kan expanderen in die eerste minuten. Zodra de korst vormt is dat niet meer mogelijk. Misschien heb je nog wat aan deze tips:…your-oven/

    Vooral als je een recept voor de eerste keer probeert kan er nog van alles zijn dat je aan jouw omgeving, ingrediënten en apparatuur moet aanpassen. Wij maken veel recepten wel minimaal 10 keer voordat we het echt in de vingers hebben. Ik kan aanraden dat je zaken opschrijft in een notitieboekje, zodat je kleine aanpassingen kunt meenemen en weet wat wel en niet werkt.

    Heel veel succes en plezier nog met bakken en geniet van het brood!


  38. Caroline says:

    Hoi Marieke en Ed,
    Vraagje. In plaats van 50gr spelt bloem kan ik ook whole wheat of rye bloem gebruiken bij het maken van de sourdough?
    Ik heb voor het eerst julie nieuwe mandjes gebruikt, maar het deeg bleef er jammer genoeg een beetje in hangen. Toch nog gebakken maar het rees niet meer dus een beetje dense. Hoort het nog wel een beetje te reizen in de oven?
    Alvast bedankt.

  39. Ben says:


    I really want to try this at some point. In the “Making the Loaf” section it says 3 minutes of mixing, but in the timetable at the bottom it says 3 minutes of kneading. Could you clarify this please?


    • Weekend Bakers says:

      Hello Ben,

      Thank you for asking. For this recipe we do our kneading in a spiral mixer with a dough hook. So if you are using a similar mixer you have to knead for 3 minutes, if you are kneading by hand I would double that to 6 minutes. So what we mend to say I guess is ‘kneading in a mixer’.

      Good luck with the recipe and happy baking,


  40. cookandbaker says:

    Hi both,

    I’d be very grateful if you could help out once more: I was wondering whether it’s possible to freeze a loaf to bake off at a later stage. If so, is this done at before the second proving, after the second proving, or at some other stage?

    Best wishes to you. Happy baking!


    • Weekend Bakers says:

      Hello Andrew,
      We do not have experience with this ourselves. We know that it is possible and people usually freeze after shaping.
      You can find more info here:…bake-later

      Good luck with it and let us know how it turns out for you, would love to learn about it too.

      Happy freezing & baking

  41. Tijen Uslay says:

    Hello Weekend Bakers,
    Excellent recipe, worked for both me and my mother, although we are beginners. How can we alter this recipe, to make the taste a bit more sour? Any ideas?? Thank you.

    • Weekend Bakers says:

      Hello Tijen,
      Great to hear! About the sourness, the challenge is in your sourdough culture, it probably does not contain enough lactic (think yoghurt) and acetic (think vinegar) bacilli . You could try to make your sourdough culture a bit less wet and stiffer and keep it in a cool place, but not the fridge, to promote development of especially the acetic acid bacilli, because they thrive in a cooler and less wet climate. Also, a younger culture tends to be less sour because of the lack of both bacteria, the older it gets, the more complex the taste of your culture can become.

      Good luck and happy baking!

      Ed & Marieke

  42. cookandbaker says:

    Hey both, thank you so much for getting back to me. I had gone ahead an knocked the air out but it still rose in the end so it was all totally fine, which was a relief. You could check out my recent ‘fermented juice sourdough’ post in which I refer to your links.
    I baked it off in a pyrex oven dish for about 50′ at 200C fan, and it was totally fine. Hope I get the same results the next time. Still surprised that I managed to get a decent loaf on Friday and today, Sunday. So hopefully so long as I keep the starter alive, I get the same results.

    Thanks once more for making your expertise available on this great resource that is your blog, and for your specific advice and clarifications.

    Happy baking to you both!


    • Weekend Bakers says:

      Thanks Andrew, glad we could be of help!
      Your loaf is looking good and the things you ate with it sounds like our cup of tea too :)
      Maybe next time you can try a little less ‘air knocking’ and see what kind of result that will give you.

      Lots of loaf!

    Hello both,

    thanks for your reply above. Also getting in touch for some clarification re a stage to the above recipe.

    I’ve attempted making my sourdough to some success (cf., my recent blog post) making a starter out of apple juice that had fermented/become sour and gassy, and plain flour. I then stirred that daily for 3-4 days occasionally feeding it till I mixed 1 & 1/2 cups of it with 2 cups of flour, and lo and behold, I made a sourdough after proving twice – firstly, for 90 minutes, and then for 60 minutes. It baked at 200C (fan) for c.60 minutes and was fine, nice and elastic with a good crust and very little inner crumb. I have more starter left which I’ve refrigerated. I have also mixed some with flour last night, kneaded it, left it to prove for 90 minutes and then for its second proving left in the fridge overnight. It’s now more than doubled and I am bringing to room temperature to bake off in about 3 hours or so. This is where I want your help: you state above that:

    “day 3 18.40 h Put dough in fridge for 15 hours
    day 4 10.00 h Take dough from fridge and leave at room temperature for 2 hours
    day 4 12.00 h Shape the loaf and leave to proof for about 2,5 – 3 hours
    day 4 14.30 – 15.00 h Bake for 45 minutes at 235 ºC / 455 ºF”

    I was wondering where you say ‘shape the loaf and leave to proof’ whether I am meant to knock the air out of the dough and let it prove again so that it doubles during those 2.5-3 hours….

    Any additional clarifications would be greatly appreciated.

    All the best,

    • Weekend Bakers says:

      Hi Tony,
      Yes, you must also double or triple your starter, more ingredients and more dough means also more work to be done to get the whole thing going!

    Hi. I’m Codruta. I wrote you a comment above a while back. Since then, I started my own adventure in blogging :) I made this recipe two weeks ago, with wonderful results. I used mixed SD cultures (white and rye) for the starter and the flavor of the bread was incredible and unique. The starter stood in the fridge for 34 hours without collapsing (maybe just 1cm, at the end of time)
    I’m doing the bread again, as we speak, this time using only rye SD culture for the starter. The rye culture is very active, and after 24 hours in the fridge it already collapsed (~ 5cm)… I’m wondering, should I wait another 10 hours, or should I deviate from your time schedule and use it right away? When you are making the bread, the starter stays at its peak the whole time, or it colapses after a while?
    Hope you’ll be able to reply in time.
    Thanx guys, you are the very best!

We’re Australians living in Japan so you are truly global!! Thank you so much for sharing the recipe, time and videos – all of which helped me. The bread was delish.. mmmwah!!

    Regards, Jane

    • Weekend Bakers says:

      Hello Jane,
      I woke up this morning and the first thing I read was your wonderful comment. I could not have asked for a better start of the day :) Very happy you like our recipes and the fact that they work so well for you!

      Lots of loaf,


  58. Weekend Bakers says:

    Always happy to help if and when possible :)
    We use an organic wheat flour with a protein content of about 13% .
    This table shows the equivalents for different countries, but in Holland we do not have these type names.…pe_numbers
    The flour we use would come close either to your 812 or 1600 type.
    The flour you use now, the 550, is lower in protein and could very easily be a big part of the problem. So this is definitely the first thing I would change when trying the recipe again (always change one thing at a time, otherwise it will be harder to pinpoint the problem).

    Good luck!


  59. colin sneller says:

    Hi Marieke
    I baked this bread today with my baking stone in at 235° and after 20 Minutes it was already very brown. So I put some alu foil over it and turned the oven down to 190°. After 35 minutes I took it out and it was obviously ready – in fact a bit too dark. Do you bake your loaves for the full 45 minutes at 235°? Maybe my oven is hotter than it says on the regulator and I’ll perhaps have to bake at a lower temperature. Apart from that the bread was great and tasted fantastic like always.
    Greetings from Colin

    • Weekend Bakers says:

      Hi Colin,
      We have a Rofco bread baking oven with chamotte stones, so it is a bit different from the regular oven most people use, but we bake on ‘falling temperature’. You can try this too, especially when your heating system is too close to your bread (e.g. if your oven is quite small). Like you said your loaf could burn and you have to adjust your temperature, or make sure that you turn your oven temp down after about 10 minutes so the spirals stop heating. The closer the top of your oven is to your bread the more heat will get transferred fast and this means quicker browning and potential burning. In this case I would turn the oven to about 200°C the moment your bread has gotten a nice golden brown color, depending on your oven this will be after about 10 minutes, maybe a few minutes more. You will quickly get the hang of it as you try it a few times.
      Hope it works and hope the lame will arrive soon now!


      • colin sneller says:

        Hi Marieke
        thanks for the tip – I tried it this second time and the crust was much better. But I do have another problem with this loaf which is that both times it didn’t rise anything like as much as yours has in the photo. Yours looks so high and round whereas mine looks more like a flying saucer ( it’s the same too when I bake the sourdough soft rolls – they stay very flat in comparison to yours). Have you any ideas? Could it be my culture? When I feed it, it always makes lots of bubbles and smells sweet and fruity but I must say it has never really doubled – at the best three quarters. Also the second time I made the san francisco loaf I mixed the dough with my stand mixer that time and the dough came out extremely soft – when I tipped them out of the proofing baskets onto the paddle they spread so incredibly it was hard to keep them on and I had to really push them off onto the stone.

        • Weekend Bakers says:

          Hi Colin,
          We think there are a few things not going as they should from your description, resulting in the ‘sci fi’ version. Firstly your starter may not be active enough to get enough rise in your dough. Make sure you use organic whole rye with enough life yeast to get a really active starter. Check out our posting on sourdough starter with recent tips and comments here…asy-steps/ .
          Another thing could be the type/brand of flour you are using has a low protein content and is not developing (strong) enough gluten to get a strong elastic dough. You could try switching flour. Another but less likely problem can be over-mixing or over-proofing, either one or a combination of both will break down the gluten in the dough. With over proofing you usually see a sort of well risen loaf that will however collapse at the slightest touch. This seems not to be the case with your loaf.
          So in short, a combination of the starter and flour used with also possible over mixing.

          Hope this helps and just keep at it. At one point you get the recipe that works perfectly for you and you will be a happy baker for life. A lot of the recipes we start out with need up to ten tries to get it perfect for our ingredients, equipment and hands.

          • colin sneller says:

            Hi Marieke
            thanks a lot for your reply. As far as the starter goes, I’ve always used organic whole rye so that doesn’t seem to be the problem. The white flour I use is called type 550 here in Germany. Which sort do you use? Should I try a higher extraction – maybe type 1050 ? I’ve always kept to the mixing times you’ve given and was wondering myself if the dough was undermixed so that the gluten was not activated enough. Anyway I’ll keep trying and I love the way your are always so ready to be involved-

    Hello Ed and Marieke,
    I was looking through your recipes and I noticed that several times you use words “whole wheat rye flour” – i am a little confused by that (maybe a language problem, english is not my native) but how can wheat be rye? I probably am making a stupid mistake but I just got so curious: I understand that wheat and rye are both types of the grain. maybe you mean whole grain rye flour?
    Could you explain this please?

    • Weekend Bakers says:

      Hi Irene,
      You are right. This is our mistake, we just mean whole rye or whole grain rye, not wheat. So no language problem for you but something we did wrong and will correct very soon.
      Thank you for pointing it out!


  62. LucMartin says:

    I have a starter that lives in the fridge and has almost the same properties as the starter made on day one of this recipe. I’ve just added it (cold from the fridge) to the rest of the ingredients listed for day three in the recipe, and i will pick it up tomorrow and see how it comes out.

  63. Luc Martin says:

    This made for a fascinating read. I had a slight obsession with this bread for a while and spent some very frustrating weekends trying to get it right. I was following the method from Baking with Passion and over time adapted it to what worked best for me, in the end i made the process longer but certainly not as long as yours!

    What flour do you use for this (and in general)? In the south of Holland supermarkets don’t sell strong bread flour other than mixes for bread machines and these are loaded with various flour improvers and gluten powder. I’ve recently started buying from a local windmill; they sell 14 different flours but they don’t have any strong flours, weirdly they do sell big sacks of gluten powder, but i really don’t want to add this to the bread…



    • Weekend Bakers says:

      Hoi Luc,
      Welcome to our little website! The SFS is a favorite but we do not make it every week. I hope you will give our version a try, we have gotten favorable feedback from other bakers about their results.
      We also go to a windmill near Haarlem called ‘De Zandhaas’ in Santpoort. We buy organic wheat, rye and spelt there. The organic ‘tarwebloem’ is our most used. It is a wonderful flour, yellowish in color, full of plant flavor and sort of buttery silky smooth. As I understand these organic flours are usually strong by nature. Nobody, not us and not the miller, knows or is busy with the gluten content of the flour here. We do get these questions about it, people wanting to know percentages, but we have to disappoint. All we know is this flour makes for great tasting bread.
      And I do not have to tell you that we agree to the staying away from the mixes and ‘improvers’ and supermarket flours.
      So suggestion: good quality, fresh organic tarwebloem, volkoren tarwemeel (whole wheat) rogge (rye) and spelt.

      May I ask do you use a domestic oven or also a special bread oven? Your bread looks good!

      Happy baking!


      • LucMartin says:

        Sound flour advice; i’ve suspected for a while that the millers in Holland don’t look at gluten in the flour. I don’t know how it works in the north, but most bakeries in N.Brabant buy their bread in from a regional bakery, so its difficult to even find someone who bakes to ask them where they get their flour or if they use a flour improver. This is why i was so happy/surprised to find someone else baking at home in NL and actually doing so on a fairly large scale!

        I have a domestic oven which according to my temp probe can reach 233 degrees. I recently bought an enormous granite stone which now sits in the oven, but i’m still working out the best way to use it so no real great improvement yet. I alternate between mixing dough by hand and in a KitchenAid, depending on how much time i have.

        • Weekend Bakers says:

          Hee Luc,
          I am afraid that there are very few ‘warm bakers’ left in Holland. Most bakeries are just stores that sell bread that is delivered from a bigger baking plant. I was afraid that the craft of my grandfather was dying out, but I am hopeful that people are rediscovering the true value of real bread. We get such wonderful reactions to our bread baking, it is a reward in itself.
          We both looked at your website and we seem to have a lot of interest in common (Macaron! for example, brewing stuff). Not afraid to try something yourself and getting to the bottom of a subject!
          If you are ever in the neighborhood give us a shout, you are welcome to visit our little bakery.

          Have a nice weekend,

        By the way the butteryness you describe with your white flour i have with my local spelt flour; it’s very dense and actually almost oily.

  64. Gill says:

    I baked 2 loaves at the weekend. To fit in with my schedule the starter had a few hours longer in the fridge at Day 2 and the dough also had longer at Day 3, so I could time it to go into the fridge at about 8pm for an overnight prove. I took it out at 7am on Day 5 and it went in oven at 8.40am. I decided to try the dutch oven method which I have not done before, so one loaf went in a Le Creuset (knob removed and hole stuffed with tin foil) and the other was straight onto a stone, with oven misted. I could not believe the difference the pot makes. I’m probably going to do all my loaves in this way now to get achieve the best possible crust. The other loaf is fine, but nowhere near as impressive. thanks for posting all your recipes. I have been recommending your site to everyone I know that bakes. Not sure if this will work but here is a public link to couple of photos I uploaded to facebook.…8fbfc27d83

      Hi Gill,
      The bread looks absolutely super! Before we had our Rofco oven we baked in a Dutch oven now and then and got some great results, although yours looks even better. We just had to remind ourselves to be very careful with the hot pan, going in and out of the oven I remember. Pan hot, hot we used to should to each other.

      Thank you so much for recommending our site, it is much appreciated and thank you for sharing your fine results!

  65. Gill says:

    Have you tried an overnight retarded final prove in the fridge with this recipe at all? I’d like to try and do the bake first thing in the morning, so I can take it fresh to a friend’s house. I should have time to bring it up to room temp. before baking. Not to worry if not, I might just give it a go and see how it turns out.

    • Weekend Bakers says:

      We have not tried it, but I can see it working. Curious to know how it works out, taste and texture also.
      Will you let us know?


      • Gill says:

        Yep will do. I’m planning to bake this weekend. I baked your mini sourdough rolls a few weeks ago, which were fantastic, so really looking forward to getting my teeth into this!

  66. Fran says:

    Dear Weekend Bakers:
    I love love love this bread. Super for sandwiches, outstanding for toast and it stays so fresh for days. Terrific texture, wonderful taste. Not to mention how proud of myself I am for making bread with my own wild yeast! That said, I am not getting any sourdough flavour – is that because my starter is still young?

    BTW I have not remembered to buy any spelt flour yet. I remember only when I get to that part of the recipe and so I’ve been substituting whole wheat instead. Does this make any difference to the chemistry or is it simply taste?


    • Weekend Bakers says:

      Great to hear Fran! Could be what you say about the starter, but with the SF the dough gets a lot of fridge time and this is particularly good to develop the sour taste, so I do not know exactly what’s happening. You should wait at least 24 hours after refreshing before using the culture to give it the chance to become fully active again.
      We too have the experience that we get different levels of sourness, using the same starter, but never overly sour. Luckily we are no fans of very sour bread, we like it subtle. But the quality and taste of the bread is always great.

      Using the spelt or whole wheat is indeed a matter of taste and not so much of chemistry, so as far as we know it will not have much impact on the sourness.

      Good luck and keep on baking and using the starter :)

      • Brandon says:

        Sorry this is really late to the game. Sourdough cultures not only produce acetic acid, but also lactic acid. These two acids give different tastes to a bread. Basically acetic acid gives more of the sour vinegary taste. This is achieved by lower a hydration starter culture and fermentation times (long) and temps (colder). Lactic acid produces more of a “buttery” flavor and is much more subtle. A starter that has high hydration levels and warmer fermentation temperatures will achieve this. Obviously the warmer temp means shorter time as well.

        I love this recipe! This and your pain rustique are my staples!

  67. codruta says:

    hi! the hydration is 65.2? I’m a bit confused, cause i calculated 66,1 (299g water, 452g flour). it is not a big difference, but if you’re correct, then i’m afraid i’ve got it all wrong… :(

      You are right because Ed just recalculated it and the difference is he didn’t count the starter culture. But he says he always does this because of the very small amount of culture we use. You could call it a bit lazy…
      Thank you for noticing, your calculation is the 100% correct one.

        Hi there,
        I know that i am almost a year late to to post something here, but to be honest i couldn’t resist the temptation of writing here, b’cus i tried to figure out out o earth Codruta calculated determined the rate of hydration of the amount of flour versus the amount of water?!!! i played with it in many different ways, still i found nothing but what you guys mentioned in your initial recipe. Flour (dough+starter)= 440 gr.
        Water (dough+starter)= 287 gr. So the rate of hydration flour vs. water is 287/440= %65.2 exactly as you mentioned in your recipe. So how did Codruta get those numbers from? And i don’t know if you guys going with this based on an error that you made and i can’t see it, or you just being kind?
        However, and in either case, you are doing a great job…so keep it up 😀

        • Weekend Bakers says:

          Hello Mike,
          Both our calculations are correct, but Codruta incorporated the 24 g of the sourdough culture, so this gives us an additional 12 grams of water and 12 g of flour extra. So that is 440 flour +12= 452 g flour and 287 water+12=299 g water . 299/4.52 = 66,15% hydration. Codruta is right to also include the flour and water from the culture in the calculation to get it exactly right. But like we said we were a bit ‘lazy’ and left the 24 g of culture out of our calculation. Usually we use a tiny amount of starter culture (10 g per bread) and we also use a rather stiff rye culture, with even less water so we do not incorporate this in our calculations. With this bread with 24 g of culture it does make a difference of almost 1% so it would be correct to take it into account.

          Apart from that, the recipe is still producing a fine loaf, worth the effort we think.
          Thanks for your comment and happy baking!

          Ed and Marieke

          • Mike says:

            Thanks Ed for your answer, though i’m late for these discussions. Well i guess you are right, Codruta got it right, where i failed. Anyway, Ed since last night there has been something in my mind concerning this bread which i love. Since i have successfully managed to make a really active sourdough culture from both Wheat flour and another one from Whole Wheat Flour (Rye i don’t have :(), my question is:
            Can i use my sourdough culture instead of making your sourdough starter? I.E: adding 233 gr. of my sourdough? and if yes what do you think the bread will look like in terms of texture, crumb, crust?
            Thanks Ed,

          • Mike says:

            Oh Ed, it’s me again.
            I have a suggestion:
            why don’t you allow people here interested in your recipes such as me to post pictures of their baking endeavors and discuss it here to see what is right and what is wrong, so everybody would benefit of that and avoid mishaps?

          • Weekend Bakers says:

            If you use a recently refreshed starter with the same hydration then of course it is not a problem and I think the result would not be that different in terms of the end result.


          • Weekend Bakers says:

            PS: At the moment we are looking into the possibility to incorporate pictures or other ways to share baking information between us bakers.

    Gary, if you ever get to the point of deciding to do the market-bake please let me know. I am just learning about production at the moment and it would be great to corespond with you. Thanks a lot!


  69. Gary Cook says:

    Thanks Ed! I’m starting to think again, knowing that even experts such as yourselves think it’s a very large undertaking. Perhaps I’ll sit the first market out or make something a bit easier.

    Hi Weekend Bakery

    Umm, just wondering something.

    I’ve been asked to make a BIG batch of these loaves for a market. If I use my rye starter to make the preferment and presumably scaling up as much as I can, as quick as I can, how can I get to a stage where I can make 100 loaves?! Do I need to scale everything up by x100 through the whole recipe, or can my starter ‘activate’ larger quantities of dough?


    • Weekend Bakers says:

      yes, it is basically scaling everything up so also the amount of rye starter. When you do not do this you risk that your timings will be off because everything will go slower with less active sourdough starter. Honestly I never made this amount of bread, the most I have baked on one day is 18 loaves in 3 batches of 6.

      At least a day (perhaps even 2) in front you need to seed a large amount of rye flour with your current rye starter. What happens is at first your current starter, rye flour and water make what they call a preferment. But when your preferment gets ‘over the top’ by letting it rest longer it turns again into a full active starter and with this larger amount of starter you can make a much bigger preferment and the circle is closed. You can speed up the process of making a bigger starter by using luke warm water 30-32 degrees Celsius because the higher temperature speeds up the multiplication of the yeast and bacteria in your new to make starter. You probably need very large tubs so all the dough can bulk ferment in two or three large chunks.

      Much success,


  71. Gary Cook says:

    It did! Thanks Ed.

  72. Gary Cook says:

    Hey Ed.

    So pleased with this. Your recipe is fantastic.

    Lovely nutty taste, moist inside and great crust, (I tried it in the cast-iron combo cooker, as
    I would have done the Tartine loaf.) A bit dark, as I couldn’t resist opening the cooker a bit
    early, will leave it inside to get more steam next time.


  73. Gary Cook says:

    Hi Ed,

    Yes, I spent the best part of a weekend making it, with poor results. My dough was (very) wet when I put it into a box within
    a box and kept the heat around the suggested 78F-82F. After the stretches and folds in the box, in the final hour the whole thing went crazy bubbly and nearly erupted out of the box. Turning it out for the bench rest it was still very, very wet and although the bread tasted nice and had a good crust, it hardy rose at all.

    In retrospect, I think I started out too wet, I don’t think I managed to really strengthen the dough with the folds and maybe all the bubbling in the final hour of the bulk rise showed that I over-proofed it?? But I only had it in the box for three hours.

    Maybe you can suggest how to get a better result if I ever do the Tartine method again?

    Will let you know I get on with your recipe. (My rye starter instantly looked very grey when mixed with water, not white-ish??)


    • Weekend Bakers says:

      The rye starter is very gray at start, it is a bit hard to capture on photo what it looks like. When the starter gets ‘older’, more active and sour it turns to a more beige color.

      Did you notice the ‘fault’ in the tartine recipe where you make twice the amount of preferment poolish than you use in the final dough? So if you like me throw in the lot of the poolish instead half of it your dough will turn out much wetter!


      • Gary Cook says:

        Ok Ed, I’m 15 hrs into the ‘starter in the fridge’ stage. Will let you know how it goes. Starter in bowl has
        got a lot larger and has a nice, creamy, bubbly appearance? Like an idiot I started the procedure 2pm yesterday, so 34hrs from fridge internment should see me baking loaf at some crazy hour, as usual!

  74. Gary Cook says:

    Hi Marieke

    I’m definitely going to try this, it sounds a bit easier and a bit more likely to be successful, than my attempts at the Tartine method.


    • Weekend Bakers says:

      We baked Tartine breads three times but although the bread tasted nice it takes just too long to make it as our staple bread. Doing stretch and folds every 30 minutes for 3 to 4 hours is just too time and labor intensive and it seems too temperature sensitive during bulk fermentation with the very low active preferment/starter.

      Although the San Francisco style bread takes a long time, it is less labor active and still yields a nice bread. We love to hear about your result!

      Enjoy baking,


  75. Weekend Bakers says:

    Thanks Mike!
    If you have any more remarks or questions, do not hesitate to let us know. I hope the bread will turn out great!

  76. Mike D. says:

    OK, I am going to make this this weekend. The pinch of yeast reminded me of your pain rustique, so I did not want to skip it if it was helpful. I have a whole wheat starter I captured and have been developing since last September and I leave it out on my bench as I make a loaf of no knead sourdough every night baked in a cast iron pot with lid, but I started a rye starter to play with and see if I like it better. I sure am enjoying all your hard work and help on this site!

  77. Weekend Bakers says:

    Hi Mike,
    I am afraid we made a mistake! We do not use yeast in this recipe, that is why it is not in the instructions, but it was somehow added in the ingredients list. I have taken it out already so the recipe is now as it should be. There is a version of SF sourdough that uses a small amount of yeast, but we have never made that version.
    Thanks for pointing it out and we will check and double check to make sure the recipes are correct.


  78. Mike D. says:

    In the recipe above you have 2,3 grams of instant yeast listed as an ingredient for the dough but never say when to add it in the step by step instructions.

  79. gbuckley says:

    I lovethe picture and want my bread to look like that and taste like sourdough. I notice you talk about the sourdough culture is this something you make or purchase?
