often jokes with students: Northerners like to eat buns, so they are tall. After the flour is fermented, the phytic acid that affects the absorption of calcium and trace elements is removed, which increases the probability of mineral absorption, and is easy to digest, which can make the stomach and stomach very comfortable. It is one of the most suitable staple food for people with weak spleen and stomach.

　　 When my daughter was young, sometimes the grandfather played noodles at home to make buns. Because there was expired milk powder at home, it was added to the flour. After putting yeast and hair, it was kneaded into strips and cut into pieces. For small steamed buns, place the lid on the drawer and steam again for 20 minutes. After the fire is stopped for 5 minutes, remove the pot. In an instant, a pot of white and plump buns with rich milky flavor was ready.

　　Using milk instead of water and noodles to make steamed bread, not only has a better flavor, but also more nutritious. After adding more calcium and high-quality protein, the nutritional value of steamed bread has changed qualitatively. This nutritious staple food is very suitable for elderly children and frail people. There is also a situation where some people drink milk will have lactose intolerance problems such as bloating and diarrhea, which is caused by insufficient lactase in the body. This situation is generally common among the elderly and children and people with digestive diseases.

　　 In fact, this kind of problem is also easy to solve, or you can use milk to ferment to make yoghurt to make lactose into galactose. Another method is to make fermented steamed buns or hair cakes, which is not only less prone to lactose intolerance, but also more conducive to mineral absorption.
