What is enriched yeast bread?
Enriched breads refer to those that are higher in fat than other breads due to more eggs, butter, and/or milk . Because of their higher fat content the dough is very soft and delicate, and often molded and baked in pans. Braiding also helps the enriched dough hold its shape during baking.
Examples of enriched yeast breads are challah, brioche, and babka/baba.
