2. Wash and peel potatoes for later use.

3, potatoes are best to choose old potatoes, fresh potatoes have high starch content and are powdery when fried, which affects the taste.

4. Cut the potato into vertical small pieces with a knife specially used for cutting potatoes.

5. Why do you use a special knife to cut potatoes? Is to make the potato pieces cut more evenly and fry better.

6. Rinse the cut potatoes with clear water, soak them for a few minutes, fully remove the starch contained in the potatoes, and then remove them and put them on a clean plate for later use.

7. After pouring a proper amount of water into the pot and boiling, put the cut potatoes into the pot and cook for 3-5 minutes. This depends on the heat, and you can also look at the color of potato chips. If the color of the potatoes is a little transparent, they can be cooked. Don't forget to add half a spoonful of salt in the process of cooking potatoes, and then take them out.

8. Control the boiled potato pieces to dry, and add starch without water at all. Some people use bread crumbs, but the principle is the same, according to their own taste.

9. Pour the oil into the pot (rapeseed oil or salad oil can be used). When the oil temperature reaches 75 degrees Celsius, put the potato pieces wrapped in starch into the oil pan. Why do we have to control dry water? Because the potato pieces have water, the oil pan will fry.

10, fry for 2 minutes on medium heat, then turn to low heat and continue frying until the potato chips are golden yellow. Take out the oil control. The freshly fried potato chips are a little soft, but they will become brittle after a while.
