These are steamed buns, and they are an extremely common breakfast food. There are about two venders on every block in the street or small booths each morning. You can choose between plain, meat, bean, vegetable, some kind of veggie curry, and some stores have more variety. It’s sort of a game to find the best shop on your route to work. I have found mine. Good safe buns, picture menu, cheap prices. Each bun is about 1 yuan, which translates to about 15 cents, and 3 is plenty for breakfast. If only I could consistently remember to peel the paper off the bottom of the bun.
