1, active yeast: If the yeast is dissolved in water or flour, little or no foam appears, which means that the activity of yeast is poor and it is impossible to make dough naturally with yeast. It is suggested that it is best to change a kind of yeast with strong activity into flour and knead it into dough again.

2, pay attention to heat preservation: when the weather outside is too cold, noodles are easy to fail. It is suggested that the pot can be wrapped in another pot at this time and then placed next to the heater, which will help to enhance the activity of yeast and make the dough more easy to rise.

3. Appropriate water temperature: When using yeast, if hot water is poured directly, it is easy to kill the active substances in yeast and affect the fermentation effect. At this time, it is best to pour a little more yeast, stir the dough with warm water or cold water, and then cover the sealed bag to let it ferment again.

4. Make other foods: If the dough is still not made after a long time, it is recommended to make other foods with dough, such as noodles, dumpling wrappers, cakes, fire and so on. No need to make it, the making method is simple, delicious and very delicious.

5, sugar method: first take out a circle in the middle of the dough, put two spoonfuls of sugar in it, then put it in a cold oven, and then put a pot of boiling water to help enhance the humidity. After an hour and a half, the dough will be pushed out.
