Wash potatoes, peel them and cut them into thin slices (note that they are thin slices, too thick will not be brittle). 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. If you want to eat spicy food, sprinkle some pepper and pepper, or get some tomato sauce. I made French fries in the microwave oven, but they were not particularly delicious. I suggest making potato chips, which are more delicious.
