First of all, sweet potatoes should be high-quality honey potatoes. If I can't choose them, I usually go to the familiar market to buy more expensive ones, because the seller knows the quality of his products, and the more expensive ones should be better.
Second, slice evenly, and then rinse the starch on it. The most important step, which many people ignore, is to boil the pot with hot water for one minute. The purpose of this is that the sweet potato slices are not easy to paste and the taste is crisp.
The third is frying. Fried with plants, palm oil is used in many large processing sites. The purpose of this is to save costs, because palm oil is resistant to high temperature and not easy to oxidize. If you don't have this condition at home, you can use soybean oil or salad oil In addition, there is oil temperature. When you put the pot on the seventh floor, spread it out piece by piece to prevent it from sticking together. Stir with a spoon. Hearing the rustling of sweet potato chips proves that the edge is brittle, about two minutes.
Fourth, repeated bombing will increase its brittleness. The oil temperature is about eight degrees, and the temperature of semi-finished products with magazines drops slightly. Put it into the pot again, take it out for about four seconds, control the oil to dry and let it cool. A plate of crisp sweet potato chips is ready.
