1. Turn off the fire after the water is boiled, put the raw chestnuts in hot water 15 minutes, take them out after soaking, and then soak them in cold water for peeling chestnuts.

2. After the chestnuts have passed the cold water, cut a knife on each chestnut with a knife, which should be deeper and look at the pulp. Then put the chestnuts into boiling water, the amount of water should not exceed that of chestnuts, and then put them into the pressure cooker.

3. If the cooked chestnut is still not easy to peel, you can put it in the frozen layer of the refrigerator after it cools, and then take it out for a while. It's cold and not frozen, delicious and easy to peel.
