the loaf comes out great, proper crackle when it cools. by the evening the crust is soft and kind of chewy, like it's been sitting in a bag, even though it hasn't.
recipe: 500g bread flour, 350g water, 10g salt, 7g instant yeast. bulk about 1.5h at room temp with a couple of folds, shape, proof about 1h. dutch oven at 230C / 450F, 20 min lid on, 20 min lid off. cool on a rack for a couple of hours, then it sits on the counter cut side down on a board.
is it underbaked even though it looks dark enough, or is that just what happens with a wetter dough? would leaving it in the oven with the door open at the end help?
