These hot dog flower buns are a Chinese bakery favorite, both in Hong Kong and in Chinatowns across the U.S.
They are typically made with soft milkbread dough created using a tangzhong, which is a mixture of flour and milk or water that is cooked to gelatinize some of the flour to hold extra moisture. It has origins in Japan and then was popularized in Taiwan and Hong Kong in the early 2000s.
