<human>: I'd like to know the difference between a brioche bun and a plain white bun?
<bot>: A brioche bun is made with a rich dough that is enriched with butter, eggs, sugar, and other ingredients. It has a flaky texture and a sweet flavor. A plain white bun is made from just flour, water, yeast, sugar, and salt. It's light and airy in texture and has a slightly sweet flavor.
