1. Add some warm water to the aluminum lunch box, which is about 40-60 degrees Celsius, then spread a steaming curtain and put jiaozi in it. If it is quick-frozen jiaozi, put a layer of oil on the steaming curtain to avoid sticking to the pan.

2. Cover the lid and boil the water. 4. Then turn to low heat and continue to cook for about 15 minutes until jiaozi is cooked.

3, turn off the fire, don't rush to uncover, stew for about 3-5 minutes, and you can take out the jiaozi and eat it.
