1. Wash and peel potatoes (it is best not to eat potato skins, which is bad for your health) and boil them in boiling water. If you like salty food, add some salt to the water.
2. Cook until cooked, take it out, put it on a plate, cool it and put it in the freezer.
3. After freezing for 20 minutes, take it out and fry it directly in 60% to 70% hot oil until golden brown.
The fried potatoes made in this way have less fat content and taste better.
