The thing that makes the Low Effort Sourdough process work so well is the usage of silicone bread moulds. These moulds remove the time consuming requirement to knead the dough and turn the process of making a sourdough loaf into something much more like making a cake.
Why does it work? The kneading process breaks down the cellulose chains in the flour and makes more sugars available for the yeast to feast on. My theory is that probably the extra water in the Low Effort dough and the unusually long rise time compensate for the lack of kneading and achieve much the same effect.
I have found that the bubbles in the Low Effort sourdough bread are not as large as in “proper” sourdough bread but, as you can see, there are plenty of smaller bubbles. The bread is also not as light and “fluffy” as is typical – but it is not a dense block either. It tastes the same though and the resulting loaf resembles a traditional peasant bread. The other characteristic I have noted is its keeping ability – the bread is truly excellent on the day it is made (freshly made bread always is) but on day 5 it is still pretty much just as good as it was on day 2.
Once you get the hang of it, the entire process detailed here probably requires no more than 10 minutes worth of effort on the part of the baker. Most of the time is spent waiting for the yeasts to work their magic.
Good luck with your bread making.
