Sourdough Bread in a Rice Cooker

Note: I’ve copied this recipe from my personal website, so that you can access it in the same format as the other content on Efficient Plant-Based Cooking. I published the original a long time ago and nowadays I would do some things differently, so at some point I might update this.

Preliminary considerations

  • The idea of cooking bread in a rice cooker has been popularised by the manga Yakitate!! Japan. At least as far as I know. – There are many more things made in rice cookers nowadays and I am not very much into manga.
  • In creating the recipe, I oriented myself on the knead-free bread (Bittman 2006, Sullivan Bread) and the sourdough things in Wild Fermentation. I further informed myself with the chapter on bread in Harold McGee’s On Food and Cooking and this article by the same author. However, the parameters for my bread are completely different: whole-wheat flour and a low baking temperature. I am not sure whether one can produce a really well-structured bread under these conditions. Finding a way will require a lot more experimentation. The current results are very much acceptable, though.
  • My recipe for sourdough is from Wild Fermentation and extremely hassle-free and simple. You can find dozens of other recipes on the web. Probably all of them will work for this.
  • Most sources call for iodine-free salt. In my experience, iodine doesn’t influence the rising, but I don’t know if it has other effects on the dear microbes.
  • If you want to eat the bread on a specific day, you have to start preparing it on the day before.
  • I am using the quite primitive Tristar RK-6111 rice cooker. You might have to adjust the quantities and especially the baking procedure to your model.

Sourdough Bread in a Rice Cooker

Prep time: 20 min – Cooking time: 2 h

Ingredients

For a 1-litre rice cooker.

  • 150 ml sourdough starter
  • 300 ml water
  • 225 g whole-wheat flour for the sponge
  • 225 g whole-wheat flour for the final dough
  • 1.5 tsp salt

Instructions

  1. Stir sourdough, flour for the sponge and water together in the rice cooker’s bowl/pot. This should have the consistency of a thick pancake batter.
  2. Let ferment for 8 to 24 hours. It should bubble well after this.
  3. Stir and knead in the other flour and the salt, so that everything is evenly mixed. The dough should be too thick to effectively stir it with a spoon, but you shouldn’t be able to knead it into a non-sticky state. I. e., it should be quite a bit stickier than a normal bread dough.
  4. Let it ferment further for around ten hours. It should rise up to just under the lid.
  5. Set the rice cooker pot into the rice cooker and put the lid on. Cover the lid with aluminium foil if it is made from glass. Cover the covered lid with something insulating. An old jumper, for instance.
  6. Switch on the rice cooker. Switch it on again after ten minutes. Switch it on after another ten minutes. Switch it on after twenty minutes. A timer with a bell helps very much with this. See below for a picture of the heating cycle.
  7. Turn the bread around and repeat the heating procedure.

Notes

  • The first hot slice of the freshly-baked bread tastes very good with cold-pressed rapeseed oil and flaky sea salt
  • Instead of sourdough it might be possible to use a quarter teaspoon dried yeast. Not tested.
  • Instead of whole-wheat flour you could use lighter wheat flour, but you would have to reduce the amount of water.
  • The bread keeps forever in a paper or linen bag, but it gets harder and harder.
  • If you accidentally have put in too much water, you can make sourdough pancakes instead of bread.
  • Currently I’m not developing this recipe, because I bought a second-hand bread machine. The higher baking temperature allows for roasting vegetables and baking breads with lots of structure-destroying stuff thrown into the dough. Very useful for using up all sorts of ingredients.
