Question: what are the three categories of yeast breads?
Answer: The three most common regular yeast doughs used in food- service operations are hard lean doughs, soft medium doughs, and sweet rich doughs. A hard lean dough consists of 0% to 1% fat and sugar. Hard lean doughs are the most basic yeast doughs. A hard lean dough is often made solely from flour, water, salt, and yeast.
