The recipe technically calls to bake the bread in a preheated dutch oven (I use a casserole dish because I don't own a dutch oven), but the dough is so sticky that if I preheat the dish and transfer the dough to it once it's preheated, I find that the dough deflates and I get a flat loaf. I tried baking the bread for a bit longer, but the outside burned and got stuck to the sides of the casserole dish. This time, I let the dough rise in the dish, and I made sure that the outer layer of the dough stayed moist while it was proofing/rising for the second time. I also tried to cut slits in the bread to help it rise, but the dough was too wet and sticky and it didn't work very well. I also brushed the lid with water and the top of the loaf with water and oil right before putting it into the oven. I baked the bread for 5 minutes longer with the lid on, and once I took the lid off, I cooked it until the crust looked like it would burn if I left it in a minute longer. When I cut into the loaf, however, the texture is still gummy.
