Wash peanuts with water until there is no sediment.
Gently press the front end of the peanut with your thumb and forefinger to make a small hole in the peanut shell. Press a small hole in all the peanuts in turn, so that it is easier to taste when cooking.
Pour the processed peanuts into the pressure cooker.
Add water, and the ratio of water to peanuts is1:1.
