The trail of links from Bitsy's about the croissants led me to
this recipe for bread. I was suspicious of the claim that bread made without kneading would, well, would do anything bread-like at all, really. But the rest of the recipe was appealing... the small number of ingredients and the long rising are both qualities I like and trust in a bread recipe. And indeed, it worked out. And was so easy!
I don't have a 6-8 quart pot that can go in the oven, so I split the dough into two and put each half in a heavy ceramic pot. This made tiny funny loaves, and I think next time I might just use one pot and see what happens. The bread didn't spring up enough for me that I feel it's likely to overgrow my pan.
Now I have bread! And can stop worrying about whether it's safe to put the ceramic casseroles in the oven, and at what temperature, because 450° is about as hot an oven as I ever use.
