The following are the specific steps:
1. Dice tenderloin or mutton, and marinate for half an hour with a little salt, sugar, soy sauce, cooking wine, pepper, spiced powder and Chili powder (add a little cumin powder to mutton).
2. Make a paste with flour, water and a little baking powder, then add a little oil and mix well.
3. Wrap the pickled diced meat into a paste, fry it in an oil pan, and remove and drain the oil. If you don't want to marinate in advance, you can brush some noodle sauce after frying, and then sprinkle some pepper and Chili powder.
