Cooking Steps

1. 

   Step1:Put all the ingredients in a container. Stir slightly. Ferment at room temperature for 12 to 19 hours. If the temperature is high, reduce the amount of fermentation powder and fermentation time.

2. 

   Step2:After 19 hours, the dough is very big. There are bubbles. It smells a little sour. If it's too sour, it means that there is too much baking powder. Fold the dough a few times. It's like a quilt. It can improve the gluten of the dough. Then make it round and ferment for another 45 minutes.

3. 

   Step3:Put a bowl of water at the bottom of the oven. Preheat to 220 degrees. Bake for 25 minutes.
