What chemical reaction happens in bread?
Bread baking is an all-natural process that involves the combination of oven temperatures, moisture levels, and flour compositions in order to create a bread that is both crispy and soft.
The bread cycle begins with the pre-baking phase which involves the mixing of the flour and water according to the recipe. The dough is then baked at a low temperature until it is golden brown and firm.
The next phase is the rising phase which involves the addition of air and moisture to the dough. The dough will then rise until it is about double in size and is at room temperature.
The final phase is the baking phase which involves the baking of the bread at a high temperature until it is a crispy, golden brown, and firm loaf.
