The sprinkling ingredients are usually cumin and chili powder and a sauce. The sauce is usually sweet noodle sauce and cumin plus a lot of food additives. I forgot the specific names. They are all sold in the local spice market. It’s about fifteen yuan per pound
One pound of ingredients and one pound of oil. First heat the oil, not too high. Then dilute the sweet noodle sauce with water, pour it into the pot and boil it. Add MSG and sugar to taste for yourself. Apply until fried. Just sprinkle some cumin and chili on the skewers
