How to make dough in the refrigerator:

1. In the first step, dissolve the yeast in warm water, mix in the flour, and add 1 teaspoon of white sugar. The white sugar can provide nutrients to the yeast.

2. Place the mixed dough at room temperature for 30 minutes to allow the yeast to multiply.

3. Then put it in the refrigerator and take it out in the morning. You will find that it has fermented several times.

4. Divide the dough into several portions, make them into rolls or steamed buns, cover with plastic wrap, ferment until doubled in size, then steam in a pot.

5. Another method is to ferment the pastry at night to make dough, cover it with plastic wrap and put it in the refrigerator.

6. The next morning, you can see that it has fermented. Put it directly into the steamer, steam it and eat it.
