Peel the potatoes and cut them into your favorite chips. Soak potato chips in water for a while to dissolve starch in water. Too much starch in potatoes will not make them brittle. Boil the soaked potatoes in boiling water for 2 minutes, take them out and cool them, refrigerate them for 12 hours, then take them out and fry them in oil pan until they are golden yellow, and the chips are crispy.
 1、 How to make French fries fragrant and crispy
 1. If you want crispy fries, the starch content of potatoes must not be too high. We soaked potatoes in water for half an hour. When we saw the water became turbid, we continued to soak in water.
 2. Potatoes should be fragrant and crisp, and should not be fried with starch. The fried potato chips just make the starch crispy, and the potato chips inside are very stuffy, which will only be softer and waxier.
 3. Put the French fries in the pot, boil for 2 minutes, then take them out and freeze them. The purpose is to cook the French fries until they are 70% ripe, so as to avoid frying them for too long.
