In order to reduce the spiciness of chili oil, you can add a spoonful of salt. The spiciness of chili peppers is relative and is usually combined with saltiness, which makes the spiciness less intense. Chili oil is a kind of condiment, and the production method is very particular. First, dry the green onions and simmer them in vegetable oil along with ginger peel and chili powder. The ratio of green onions, ginger peel and chili powder is about 50:1:16. When the oil gets hot, add the chopped green onion and minced ginger. The oil temperature needs to be carefully controlled so as not to overheat the oil. Then, put 1 tablespoon of Sichuan peppercorn powder in a colander, and use a spoon to scoop out warm oil to rinse the Sichuan peppercorn powder. After all the oil has been scooped up, add 1 tablespoon of ground sesame powder and place it in a colander. Scoop out the same oil and rinse the sesame powder.
