Practice 2: Wash the potatoes, peel and cut into thin slices, and spread the potato chips on the plate, only one layer. Turn on the fire for 4 minutes, and then turn the potatoes for another 4 minutes. If it doesn't feel crisp, you can bake it again. If you take it out for the first time and think it's almost enough, turn it less for a while the second time. Generally, it will be brittle after cooling. You have to master the temperature yourself. Sometimes 1 minute will burn. You'd better watch it and come out before it gets darker, because it will burn soon. If it is not crisp enough, it should be reheated for dozens of seconds. The heat is just crisp and won't burn. If you want to eat spicy food, sprinkle pepper and pepper, or get some ketchup. You can put nothing before baking (original flavor); You can also sprinkle some salt and black pepper, which is delicious!
