Usually, 7 or 8 steamed buns can be put in a steamer and steamed for about 20 minutes. If the steamed stuffed bun is the same size as the steamed buns eaten in peacetime, it can be cooked in 15 minutes.
Tip: Steamed buns with meat stuffing take longer than steamed buns with vegetable stuffing. For example, steamed buns with pork stuffing need to be steamed for 5 minutes. Generally, steamed buns with vegetarian stuffing take 15 minutes, and steamed buns with meat stuffing take about 20 minutes.
