How long does it take to ferment about ten catties of flour on a hot day?

If there is enough dry yeast, for example, if I put 5- 10g in a catty of flour, it will take about an hour if the temperature is about 40 degrees. If it is room temperature without heating in winter, it may take more than 8 hours.

In addition, don't use too hot water for the live noodles, it will burn the yeast to death. It is best to use warm water or cold water at 30-40 degrees.

Fermented dough can be at least twice as long. As long as you press a small nest by hand, the dough will not recover.

Tmall us wechat reminds: remember to protect yourself when traveling in foggy days.

Finally, I don't think it is necessary to seal the bowl with plastic wrap, but cover it with something to prevent the dough from drying out.
