The process of fermentation is the process of cultivating yeast. Its mechanism is that a small amount of polysaccharide is decomposed into water and carbon dioxide by breeding yeast. These small carbon dioxide particles in the dough will expand when steaming or baking, thus making the dough white and soft.

The dough making process is as follows:

1. Add a little sugar and a little salt to a bowl of clean water.

2. Microwave to 30~40 degrees (about one minute)

3. Add a flat spoon of active dry yeast (available in the supermarket. If you can't find it, ask the clerk where the yeast is.

4. Stir well to make the yeast dissolve (it looks a bit like mud soup)

Use this "mud soup" to mix noodles until you feel comfortable.

6. Keep it in a warm place at 30~40 degrees (do not exceed 70 degrees, otherwise the live yeast will become dead yeast).

7. Wait 15~20 minutes. Pressing a hole with your finger after facial hair will not rebound.

8. Add a little dried noodles to adjust the feel

9. Make it into the shape you want. If the noodles continue to grow too fast in this process, you can consider putting them in a cool place, such as a window. Yeast stops growing at low temperature, but it will not die.

10 If you feel that the dough is not ideal, you can wait for a period of time after processing and shaping to let the yeast continue to grow.
