A personal quest

It all started with a gnome. A gnome taking form as a bread baking machine, which rises at night instead of me, throwing a couple of wooden blocks into the oven to start getting his hands dirty. Daily bread with a push of a button. In 2010, I did not know better. It took me two more years before my interest in the bread baking process was triggered, which eventually led to sending the gnome on retirement. Thanks to bread baking blogs such as ‘Weekend Bakery’ and ‘The Fresh Loaf’, I discovered the wonderful world of ‘sourdough’, a discovery that would change the rest of my life.

As a software engineer, I often ask annoying questions, such as ‘why does this work like that?’ Debugging the bread baking algorithm.

Since then, the personal quest for the taste and science of bread began. As a software engineer, I often ask annoying questions, such as ‘why does this work like that?’ The debugging of the bread baking algorithm. Bread baking slowly but surely started to evolve from a necessity into an obsession.

In search of that one perfect slice of bread I had tasted during my childhood holidays in Spain, I continued my search. I enrolled in evening classes and after three years of sweating in front of the oven, I became a certified bread baker. Dissatisfied with the lessons about bread during the training, I looked for an internship, which I found at De Superette in Ghent, where they bake real bread – with sourdough, of course.

My second biggest passion, besides baking bread, is sharing knowledge. Those two passions turned out to be perfectly combinable. Workshops were followed and given, my own bread-related website ‘Red Zuurdesem’ (save the sourdough) was set up, I talked with national and international bakers and, pondered on long thoughts about yeasts and lactic acid bacteria.

In 2017 the idea arose to write down everything I know about sourdough in the form of a book. Not only did I want to share my personal quest, but also to be able to offer educational value with a solid theoretical basis. What about the microbiology of fermentation, for example? Thanks to very helpful and equally passionate people, the idea took shape, to eventually be published in 2020 as ‘Save Sourdough: A personal quest for the taste and science of bread’.

After ten years of baking I am still not done talking. There are still so many things to discover: I could buy a small mill and grind grains myself, I could take some more international internships, I could finally get the baguette shape under control, and so on. It’s so much fun to be part of a baking community!

Recipe for Farmer’s wheat bread

I would like to share with you my ‘farmer’s wheat bread’ formula from the book – a combination of rye and wheat that is bound to Belgium and the Netherlands: a region that lies between the wheat-loving South and the rye-eating North. Farmers used to harvest wheat that accidentally contained a bit of rye: masteluin, a ‘terroir’ (local) grain, was created. I can’t imagine bread dough that doesn’t benefit from a little added rye flour.

The bread contains 15% wholegrain flour and 70% water. You will have to adjust the latter depending on your local flour – that is the wonderful thing about baking bread: it is constantly feeling and adjusting! I like to keep the dough simple: It’s just 10% of the total flour and the same amount of water. If possible, I always ferment the wholegrain part: the spicier, the better. You mix the ingredients 12 hours in advance and leave to ferment at room temperature.

Ingredients for the preferment
50 g Rye flour, whole grain
50 g Water (room temperature)
10 g Sourdough culture
Ingredients for a farmer’s bread
For 1 loaf of 870 gram
The preferment of day 1
425 g Bread flour, T65
25 g Rye flour, whole grain
300 g Water
11 g Gray sea salt

The long chilled second rise requires a little more salt, but the result is a flavor bomb!

Method:

  • Day 1, 08u00: Sourdough culture out of fridge. Refresh at room temperature.
  • Day 1, 20u00: Make preferment at room temperature. Put culture back in fridge.
  • Day 2, 10u00: Autolyse.
  • Day 2, 10u30: Add salt. Knead. First rise at 24°C.
  • Day 2, 15u00: Shaping. Second rise in fridge at 6°C.
  • Day 3, 08u00: 50 minutes baking in preheated oven at 235 ºC.
  • Day 3, 08u50: Cooling and trying to wait before tasting.

This formula takes at least 30 hours in total. That seems like a significant amount of work, but it is not: after all, fermentation times do not require action beyond patience. My (rye) sourdough starter culture contains equal amounts of flour and water, just like the preferment of this formula. The long chilled second rise requires a little more salt, but the result is a flavor bomb!

    Do you have a rye sourdough starter recipe? My grandson is allergic to oat, wheat, milk and eggs. I would like to make him a tasty bread option.

    Hello Wouter,
    did you know that there is a “sour dough hotel” in Sweden I think (or maybe Finland) near the airport !! where people can “park” their sour dough starter during holiday and somebody is looking after it! I almost cracked when I hear this.
    Happy baking
    Agnes.

      Hello Agnes,
      Makes you feel better about the world and people already. Thank you for sharing this Agnes. Wonder if this is the only one in the world or if there are more?!

      Yes indeed, crazy isn’t it! I need to move to Sweden 🙂 I bet the bread is much better than here in Belgium! Actually, there’s a short section about this in my book.

      Hi Maree,
      Unfortunately, not at the moment, no. It was difficult for me to decide to write it in Dutch, but as it is my mother language, I find it easier to express myself in. However, if the book has success in the Dutch speaking countries, I am more than willing to translate it. Of course, that also takes a lot of work, so I could not say if or when it will be published in English…

        Google translate does a good job with your website. I’d imagine that machine translation as a first pass would reduce the initial workload to translate your book. Looking forward to trying the Farmer’s bread. The preferment is almost done

        After nine seriously good Farmer’s loaves I owe a big thank you to two people: to Wouter, who took the trouble of sharing his knowledge on the net and to my dear Dutch friend, Henriette, who set me on the ‘sourdough path’ years ago, never gave up on me and sent me the link. I now find joy in baking and the family are delighted! THANK YOU!

    I sent a picture of my loaves to Your Loaves. The shape is not as perfect as I wished, the dough was sticky…

      No worries! Maybe your flour did not readily absorb as much water as mine does. Simply reduce the water percentage – 65% is a safe start. You can work your way up if you want to. Or not. In my view, the dough should still be easily workable – although everyone these days loves pushing the water content to the limit. That was not my intention with this recipe, so again: feel free to reduce! Good luck!

      Thanks Laura! I had to take the shot a couple of times because of the light settings. That meant feeding the starter again, and waiting until it burst out of the jar, again… It was a lovely day, watching bubbles appear and taking a photo at the right moment!
