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!

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).
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 for around 750 grams of dough. 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.

Keith McNenly says
Just tasted my first try at San Francisco style sourdough bread. Four day resting, folding counter and fridge fermenting process but well worth it. A nice caramelized crispy crust, great chewy texture and perfect sourdough flavour and distribution of small and large yeasty bubbles. I guess it’s all in the time and process of slow fermentation to get the flavour, but the exquisite moist chewy texture was totally unexpected and a very pleasant surprise. I tasted that flavour and texture at a fine dining restaurant where I had the opportunity to sample their range of house baked breads decades ago and not since. Baked it in a Dutch oven with lid using parchment under it to move it.
Eva Mullendore says
why don’t the recipes for sourdough bread use cups as measurements instead of grams? It is so hard to figure out the conversions from grams to cups.
Ross Phillips says
because baking is science and needs to be accurate………….
Martin says
Absolutely. Cups DO vary, and in something as finely balanced as Sourdough bread you need accuracy. Cups won’t work
Tove Gisselbæk says
I bake this bread again and again. It’s the Best 🤩🤩🤩
… Now i only need to make myself a betyder sourdough culture, it’s not always strong enough to rise the dough 🤦♀️😀

Christa says
Thank you for sharing this process. I am a culinary student working on my Independent Study Project and writing a paper on sourdough bread. I found this site through a link and read it over many times. Being from the S.F. Bay Area and now living further away…this truly brings me back home. My first loaf came out of the oven this evening and it was a game changer.
Thank you!
Kaye Ferguson says
Hello,
Where do you get the culture for the starter or can you make it? Thanks, I am new to this.
Christine K says
They have clear instructions put up in here below.
Foolproof if followed exactly.

Deb says
I am confused about making the starter, the directions are not clear
Fero says
You need to have your sourdough mother first feed it when fed and bubbly take 24g add flour and water mix well cover with cling film and leave it to rest for min 9 hours
Christine K says
They have put in clear instructions below.
Absolutely love their details on every step.

Heather says
When using a Dutch oven how do you keep your bread from burning on the bottom, I always have a problem with that and then the bread is really hard to cut through the bottom
Annemiek van Moorst says
Try with a lower temperature Heather (I had the same); like for example not 235 Celsius but 225 or 230. Depending on your Dutch oven – do not overdo the preheating.
Most breads do well in my Dutch oven with oven temp. 30 min. on 230/225 and 15 minutes without cover on 225/220 when indications are slightly higher (235 for 45 minutes).
Fero says
I have got same issue with my Rofco B20. Bread on boytom shelf is almost always burnt.Any suggestion how to avoid it please??
Dawna K says
Ive had great luck placing a trivet in the bottom of my Dutch oven (i use one that came with my old pressure cooker). You can also put a layer of rice or cornmeal between your parchment paper and the Dutch oven.
The last helpful hint i just received is to fold a large square of parchment paper into fourths and place that under your loaf -I haven’t yet tried this one but sounds promising, you can reuse parchment paper for this.
Peter says
I always put a backing stone on the shelf below my Dutch oven !
Angelika says
I used to have the same issue but came across someone using ceramic pie weights in the bottom of the Dutch oven. Heather, it works like a charm, fill the whole bottom of your Dutch oven with a single layer of ceramic pie weights and you will not have a burned bottom crust again.
Annette says
I have tried your ceramic beads tip. Worked brilliantly! Crusty on top but sliced through easily at the bottom. A £5 well invested. Thank you.
Nestor Holynskyj says
I cut out a circle of parchment to line the bottom of the Dutch oven. I’ve used it over and over again with no problem.
Petra says
Amazing recipe, thank you 🙏🏻
I live in a country where spelt flour, or other specialty flours, are not always available. With what type of flour can I replace the spelt flour when I run out of stock? For the bread flour I normally use 00 flour.
Heather says
New to baking trying to get myself prepared. I have a rye starter 50 % flour 50 % water that’s 40 years old I bought from a bakery, it’s been fed for 3 days I now have way too much! I also have two round 10″ bannetons and a scraper and a blade for slashing the bread. In your recipe you say sourdough culture. Does that mean mix 24g of my starter with flour and water to make the first step that you call starter, or what I have is already ready to bake with and I skip ahead? Bit confused. Also I’ve read a lot about ‘autolease’ which doesn’t seem to be referenced. Total confused novice, help!
Rene S says
What you got is a sourdough culture and you can get you the base sourdough from it as explained (called starter here). If you have too much after feeding, you can bake directly with it aka skip the starter step and go to the main dough part directly BUT you might not get the same result, because it has fermented differently. That is rather for the expert in you… after more training. Stick to the recipe first.
Autolyse is a way to let the dough gain structure by letting it rest without salt for about 30 min. That helps to save on kneading. Not required. Just a technique you can use. Folding later does the same. Experiment with that.
Tabitha says
What would be the max time that I can leave my starter out of the fridge before putting it in the fridge for the 34 hours? Could I possible leave it out for say 19 hours lol?
Rene S says
It will be probably overfermented and hence not good for baking anymore. Stick to the times and start experiments later. Every 5C up or down increase or decreases the time for the dough/sourdough by factor 2.
Dhanoutie singh says
Hello
Thank you for the starter and
What is the best flour.( all purpose,
Bread flour or all purpose bleached flour. For the starter what is the best flour to use.
Also can you kindle send me a recipe.
Thank you
Dhanoutie singh
Richard says
I had high hopes with this recipe, it works well around my working hours. Everything went fine, but the dough did not rise as expected, despite being extra careful while folding.
Maybe you have a few tips for me.
Thanks
Weekend Bakers says
Hi Richard,
Make sure your sourdough culture is up to the task and refreshed / fed the day before use.
Also make sure the dough has the right temperature and the room is not too cold for the final proofing.
Hope you will give it a few more tries, it is worth it in the end.
Rene S says
When you don’t get the volume in the last 2-3h phase, just extend it. As long as the dough comes back fully when pushing in gently, you can extend the fermentation time. If a small dent remains and does not go away, it is time for the oven.
Silvia says
Hi Ed & Marieke.
Best recipe ever! Brings me back to my years in SF. Baking it for the 4th week in a row now. I use a Dutch oven to get the crunchy crust. Next challenge is to make breadbowls with this recipe to fill with clamchowder. I think one loaf is around 3 bowls, don’t you think?
Thanks!
