1, it is best to choose 1-2 sweet potatoes with red skin and yellow heart, and wash them. 2. Peel the sweet potato. First, cut the sweet potato into pieces half a centimeter thick with a common kitchen knife. 3. Cut the potato slices into strips half a centimeter wide.

4. Soak the cut sweet potato strips in salt water for half an hour to absorb some salty taste; French fries soaked in salt water can remain white for a long time and the body surface is not oxidized. 5, pour a lot of oil into the pot, 70% hot French fries, and then warm fried French fries. Stir the chips with a spoon from time to time when frying to prevent them from sticking in the pot. 6, fry until the French fries turn golden yellow, then remove them, and let them cool and drain off the excess oil. Don't fry French fries until they are brown. They are too much and taste like biting a stick. (If you are not sure about the degree of frying, you can try one or two French fries, and feel that the taste is almost the same as that in KFC. ) finally sprinkle with salt and pepper and eat. You can also eat it directly with ketchup.
