The time required to make steamed bread dough depends on the change of the ambient temperature of the dough. The higher the temperature, the shorter the time required, and the lower the temperature, the longer the time required. The suitable temperature is 28 to 33 degrees, and if it is lower than 20 degrees, it should be heated to 30 degrees and kept warm. It takes about three to four hours for hair with 30 degrees to appear. You can check it after two minutes, and you can see that the dough is fat and soft. You can make steamed bread when you open the dough. After making steamed bread, put 15 to 30 minutes, then steam, steam 15 to 20 minutes. Do it once or twice and you will have experience. There is no mystery. Eat better noodles. If it is sour, add a little edible alkali.
