This is not a technical job. First of all, it is necessary to foam the flour. This is the most important thing. Use the old flour as a primer, cut into strips of about 7cm, cut a knife in the middle, pull the strips before putting them in the oil pan, fry them in hot oil, and then turn them over quickly. There are a lot of practices about Sichuan snacks on the Internet. Pay attention to the fact that the flour must be foamed and the fried fritters should not be crispy.
