The so-called “screech oil” is, in fact, the distribution of spices on processed foods, such as dry peppers, sesame, garlic and so forth, and then the hot oils are poured up, and when the hot oils are caught in cold foods, they make noises and are called “screech oils”. This practice, which usually does not use too much oil, is healthier than traditional cuisine, is relatively low in heat, eats well, does not get tired of eating well for the season, and is simple and can be done in minutes。
