Brioche is an example of which dough family?

• A. Lean dough
• B. Laminated dough
• C. Rich dough
• D. Quick bread dough

Answer: (C)

The main idea is recognizing doughs by fat content and leavening method. Brioche is classified as a rich dough because it contains a substantial amount of fat and dairy, notably butter and eggs, sometimes milk. That high fat content tenderizes the crumb, adds richness, and gives brioche its soft, luxurious texture and slightly sweet flavor. Lean doughs, by contrast, have little fat and rely mainly on flour, water, and yeast, producing a chewier, crisper crumb. Laminated doughs involve folding fat into dough to create many thin, alternating layers—think of croissants and puff pastry—so brioche isn’t made that way. Quick bread doughs are leavened with chemical agents like baking powder or soda and do not use yeast, which is another big difference from brioche. Because brioche uses yeast and a lot of fat, it fits squarely in the rich dough category.
