For me, sourdough bread is perhaps one of the purest examples of how natural growth processes can be utilised to create something sustaining and delicious.
Flour and water are combined, and left as a food offering to the yeasts and bacteria that exist all around us. Over time, and with extra food, this mixture grows sufficiently in bulk and strength that with the addition of yet more flour and water, the resultant dough can be kneaded and proved and ultimately baked.
Learning to bake sourdough bread has been one of my projects for the last couple of years. With every completed loaf, my knowledge and confidence also grows.
