1 、Rice wine and water stir well, as shown in the picture.

2 , add the flour, stir into the batter.

3 , insulation can be fermented at about 30 degrees, summer room temperature fermentation is very fast, winter room temperature fermentation will be very slow, but still need room temperature fermentation, but the time takes more than ten hours. Yeast fermentation increased in volume by 2-3 times, you can see a lot of bubbles. This yeast paste is fermented.

4. Add all the flour to the paste to form a moderately soft, stiff dough. You need to add water for this step and the amount of dough depends on the dough and hard dough.

5. Continue fermenting to increase the volume two to three times. When you scoop out the dough, you can see the pores just like a honeycomb. The dough is ready to ferment. The fermentation time is 2 hours.
