You can spend the night with yeast in winter. Generally speaking, in some places, the temperature is relatively low in winter, and it takes a long time to make noodles. If it is cooked in the afternoon, it can be used overnight to the next morning. If it is summer, overnight yeast dough is not recommended. If you stay overnight for too long, the dough will become soft and the cakes will become sour.

Yeast is a fungal organism, which can be made into dry powder for easy storage. This creature has strong viability. When it is fermented, it can produce carbon dioxide and some other substances. Yeast is always active in the process of fermentation.

The fermentation speed of dough is closely related to temperature and yeast quantity. If these two conditions are not met, the fermentation speed will be very slow.

If you make dough in summer, you can add a small amount of yeast to make dough rise, and you can add more in winter, which can improve the fermentation speed of dough from the amount of yeast.

When fermenting with yeast, you can stir with warm water of about 30 degrees and let it stand for a period of time to activate the yeast. Be careful not to add boiling water, which may destroy the activity of yeast.
