<human>: I'd like to know the difference between a brioche bun and a plain white bun?
<bot>: A brioche bun is a sweet, rich yeast bread that has been enriched with butter, eggs, sugar, and other flavorings. It's usually baked in a special pan called a brioche mold. The result is a light, airy, fluffy loaf of bread with a slightly chewy texture. Plain white buns are made from dough that has been mixed together with water, yeast, salt, and flour, then allowed to rise before being shaped into rolls or buns. These buns tend to have a softer texture than brioche buns, but they still taste delicious.
