The dough should be "smooth", smooth (dough surface does not stick to hands), smooth (hands do not stick to noodles) and smooth (pots do not stick to noodles). After reconciliation, cover the pots with a wet cloth, put it in a warm place for fermentation, and put it indoors in summer, and put it on heating in winter, but don't put it in the sun! The fermentation time is about 1 hour.
2. After the fermentation, the dough smells slightly sour. Take out the fermented dough, put it on the chopping board with thin noodles, add some flour and knead it into non-sticky dough, and wake it up for ten minutes.
3. At this time, you can make steamed buns. After you finish, you have to wake up for 20 minutes. In the meantime, prepare a steamer, boil the water in the steamer, and then put the steamed buns in the steamer. The steaming time is 15 minutes, with less water added, and the dough is kneaded harder.
