Step7:7. Spread the dough evenly to the bottom of the pressure cooker. Power on the pressure cooker for a few seconds. It's hot inside. The temperature is no more than 40 degrees. Put the inner tank of the pressure cooker with dough into it. It can help ferment when the weather is cold. It's not needed in hot weather.
Step8:8.22.5 hours (the fermentation time depends on the temperature. Here is for reference only) the fermentation of the back dough is twice as large as the original one. Sprinkle clean Lycium on it and dry it. Press it onto the dough. You can also add walnuts, cranberries and other things as you like. The reason why fermentation works well is that we are worried about the influence of putting it in advance on the taste. Power on the pressure cooker. Close the air valve for 15 minutes.

Cooking tips:1. The advantage of this method is time-saving. The disadvantage is that the bottom color may be golden, like the baked color. It is not as beautiful as the steamed bottom. But if the steaming time is short, it is not easy to steam through and it will stick to the teeth. 2. The water in different areas will turn blue or dark if it is hard. You can add a little white vinegar. The color will be beautiful. There are skills in making delicious dishes.
