Baozi (Chinese: 包子), or bao, is a type of yeast-leavened filled bun in various Chinese cuisines. There are many variations in fillings (meat or vegetarian) and preparations, though the buns are most often steamed. They are a variation of mantou from Northern China.
Two types are found in most parts of China and Indonesia: Dàbāo (大包, “big bun”), measuring about 10 centimetres (3.9 in) across, served individually, and usually purchased for take-away. The other type, Xiǎobāo (小包, “small bun”), measure approximately 5 centimetres (2.0 in) wide, and are most commonly eaten in restaurants, but may also be purchased for take-away. Each order consists of a steamer containing between three and ten pieces. A small ceramic dish for dipping the baozi is provided for vinegar or soy sauce, both of which are available in bottles at the table, along with various types of chili and garlic pastes, oils or infusions, fresh coriander and leeks, sesame oil, and other flavorings. They are popular throughout China.
In many Chinese cultures, these buns are a popular food, and widely available. While they can be eaten at any meal, baozi are often eaten for breakfast. They are also popular as a portable snack or meal.
The dish has also become common place throughout various regions of north Asia with cultural and ethnic relationships, as well as Southeast Asia and outside Asia due to long standing Chinese immigration.
