It seems that baking powder is used to make flour food, but of course, steaming steamed bread can also make flour food mellow. Its method is very simple. It takes much longer to make a steamed bun than to use baking powder. However, the surface of the steamed bun will be white and soft, and the taste will be relatively good because it has not experienced acid gas. Note that the fresh-keeping bag is used to cover the basin during the whole process of naturally mellow, and it is confirmed that the dough is good when the paste is uneven.
 How to make steamed bread with self baking powder
 First prepare the required raw materials, find a washbasin that can knead, and then take two bowls of wheat flour and put it into the washbasin (a bowl for ordinary meals). The wheat flour should be used better. The steamed buns made like that can be white, beautiful and delicious.
 Sprinkle the prepared yeast in the wheat flour (just put a small spoon in the small rice spoon, if there is more wheat flour, you need to put more.), and put a little soda ash in order to make it not easy to have sour taste after it becomes mellow. Then mix them evenly.
 After mixing, put water in and rub the wheat flour into batter. What should be noted here is that; In the case of water discharge at the beginning, it is not necessary to add too much at one time. A little bit of water, if put more, the wheat flour will be very thin, can not make batter. Only when the wheat flour is small, if the wheat flour is still a little hard, add some water until it can be rubbed to a lump.
 After kneading the batter, use a fresh-keeping bag or a cover to cover it and wait for it to rise. When you see many bubbles in the batter, it will be clear that the batter has already become mellow.
 Then take the dough and make it into a long oval shape on the control panel. Then use a knife to cut it into sections. The spacing need not be too big, or it will look ugly. After cutting, wait for more than ten minutes to let it mellow for a while. Since the steam bubbles in the noodles have been pressed down just after kneading the development strip, it will take a while before they can be put into the pot. It also makes the batter more puffy and tastes stronger. After waiting for more than ten minutes, it can be put into the steamer to steam. Steam for 15-20 minutes.
