Baking the Bread
The various processes in the making of bread that have been considered up to this point may be successfully carried out, but unless the baking, which is the last step, is properly done, the bread is likely to be unpalatable and indigestible. Much attention should therefore be given to this part of the work. So that the best results may be obtained, it should be borne in mind that bread is baked for the purpose of killing the ferment, rupturing the starch grains of the flour so that they become digestible, fixing the air cells, and forming a nicely flavored crust. During the process of baking, certain changes take place in the loaf. The gluten that the dough contains is hardened by the heat and remains in the shape of bubbles, which give the bread a porous appearance; also, the starch contained in the dough is cooked within the loaf, but the outside is first cooked and then toasted.
