I don't make sourdough anymore because I just don't have time for it. For our normal use we make two 250 gram boules a week as expeditiously as we can. A great tool that I discovered a few months ago is this silicone bread baking bowl. If used as intended it makes a ridiculously shaped loaf - looks like a football and frankly - it sucks. BUT you can mix, knead, and rise right in the bowl, and since nothing sticks to the bowl clean-up is a breeze. I divide a 500 gram dough in two and bake in a couple of dutch ovens we keep for the purpose. If you are doing a single loaf this bowl, a spoon, and a measuring cup are all you need - and all you have to clean up. It's been a huge time saver for us.
