Mix flour and flour into dough and let it stand for more than four hours. When the dough is fermented to twice its original size, it will ferment. Add an appropriate amount of alkali to neutralize (alkali and a little water are better kneaded into the dough), and add it bit by bit to avoid excessive addition. When the dough is smooth and non-sticky, it means that the alkali is moderate, put it aside, cover the basin with a lid or cover the dough with a cloth, and wake it for 40 minutes; Make the dough into steamed bread shape and wake it for 20 minutes; Steam on the pot, put a proper amount of water in the pot, and serve it after the water is hot (steamed bread is softer and more delicious without cooking).

1, dough, refers to the process of dough under certain temperature and humidity conditions, which makes yeast fully propagate and produce gas and promotes dough expansion. When yeast converts starch into sugar and consumes it in the aerobic environment inside the dough, it will release carbon dioxide gas. At this time, the volume of dough will expand and rise.

2, hair noodles, also refers to fermented noodles. Famian was discovered by accident during the development of pasta. Humans have used yeast to make Famian for 5000 years.

3. For health, use half whole wheat flour, add half white flour, pour it into the basin, poke a hole with chopsticks in the middle, pour a little water, and add a proper amount of yeast powder. "Appropriate amount" can be seen in the instructions on the yeast package. You may be inexperienced at first, and there will be problems with putting more and less, but it doesn't matter. If you put less, the fermentation time will be longer, and if you put more, it will have no effect. The key is to see the production date and shelf life of yeast clearly, and expired yeast can't stand it.
