1. The beef is minced with a machine, and a small amount of sweet potato powder is added and mixed well (the sweet potato powder is tender and smooth, so sweet potato powder is preferred)
2. A little water starch (add a little water to sweet potato powder)
3. Underwater pot, put the ginger. Add seasoning soy sauce and monosodium glutamate (the restaurant normally uses beef stock, and the ginger is put in when the ginger is cooked)
4. The beef soup is cooked irregularly with your hands, not too thick
5. Cook for a few minutes. After seasoning, blend with water starch and make it thicker. [Water starch should not be too much too thick] Add a few drops of sesame oil to the garlic
6. Add a few drops of old vinegar when you eat it is pretty beautiful
