What is the reason why steamed bread blooms

1, the dough is excessively fermented, which greatly reduces the strength of the dough.

2, improper molding, low humidity in the process of proofing, resulting in cracking of the skin when steamed bread.

3, the blank is not smooth, the steam is not enough when steaming, and the surface of steamed bread is easy to crack.

4. The fire is full of gas, and when the blank is heated sharply in the cage, a large amount of dynamic carbon dioxide gas is generated inside, which escapes from the top and bursts.

Steamed bread, also known as "steamed bread", "steamed stuffed bun" and "steamed bread", is one of the traditional pasta in China. Legend has it that it was invented by Zhuge Liang, the prime minister of Shu and Han Dynasties in the Three Kingdoms, and it is a kind of food steamed with fermented flour. Steamed bread with wheat flour as the main raw material is one of the daily staple foods of China people. Legend has it that Zhuge Liang invented it during the Three Kingdoms period. Romance of the Three Kingdoms tells the story of Zhuge Liang's capture of Meng Huo in the seventh place. After the barbarians were pacified, the crossing of the river was blocked by the dead ghosts. Zhuge Liang was worried about this scene and thought about it, so he had to pay homage to the river god, pray for God's blessing, punish evil and promote good, and bless all beings. Zhuge Liang could not bear to sacrifice his head and invented steamed bread as a substitute. So he ordered the sheep and pigs to be slaughtered, wrapped into dough and thrown into the water as sacrifices. Later, people learned this custom. This is probably the origin of "steamed bread". "Man" means "man" and "steamed bread" means "head". Steamed bread is a food made by mixing flour with water and sugar, fermenting and steaming. The finished product is hemispherical or long. In Jiangnan, this kind of pasta with meat, vegetables and bean paste is called steamed bread, and steamed bread without stuffing is called solid steamed bread. Delicious, soft and nutritious, it is one of the essential staple foods on the table. Different tastes and practices have led to the development of various steamed bread, such as white flour steamed bread, corn flour steamed bread, vegetable steamed bread, meat steamed bread, raw fried steamed bread and fried steamed bread with different names.
