1, exposed to the hot sun
After the raw chestnut is ripe, the water on the surface of the chestnut shell will automatically crack after being exposed to the hot sun for a few days, so it is easy to remove the shell.
2. Microwave oven
If there is a microwave oven at home, you can cut a small opening in the raw chestnut shell with scissors and bake it in the microwave oven at high temperature for one minute. After taking it out, the shell will be separated from the pulp.
3. Refrigerator freezing
Put the raw chestnut in the freezer of the refrigerator for two hours and take it out. Because of heat expansion and cold contraction, the fruit of the raw chestnut will shrink and separate from the shell, so that the shell will crack when you pinch it with your hand.
4. Cook in boiling water
There is also a method that the raw chestnut is boiled in boiling water for four or five minutes, and then immediately taken out and soaked in cold water for five minutes, so that the shell of the raw chestnut will be easily peeled off after it is separated from the pulp.
5, light salt water to boil
Another method is to boil the light salt water, soak the raw chestnut for five minutes and then take it out. In this way, not only the shell of chestnut but also the skin inside will be easily peeled off with the shell.
