1. Adding 1-2 tablespoons of sugar when melting baking powder can make the dough ferment better.
2. When melting the baking powder, it is best to melt it with warm water not exceeding 40℃. If the water temperature is too high, baking powder will lose its activity and affect dough fermentation.
3. When kneading dough, if the dough feels sticky, you can add a proper amount of corn oil. At the same time, avoid the dough being too dry, or the buns will be very hard.
Because the dough is soft and easy to knead, it should be as smooth as possible.
5. Cover the wrapped buns and continue to simmer for 20-30 minutes, because some air in the dough is released when rolling, and continuing to simmer on a small fire can make the buns more even and full (this step is crucial).
