Oxtail stew: 2Kg oxtail (water 10L￠, 3 onions and 5 garlic), salt, pepper and appropriate amount of onion. Seasoning for meat: 1 tablespoon soy sauce, 2 tablespoons salt, 2 tablespoons chopped green onion, 1 tablespoon mashed garlic, 1 tablespoon sesame oil, a little pepper. Practice: (1) Cut the oxtail into 4-5cm, or when buying the whole piece, insert a knife into the cartilage between the joints to cut it off, scrape off the adventitia, soak it in water, and take it out after bleeding. (2) Cook oxtail in boiling water for a while, then lower the heat and cook for about 3 hours. When cooking, cut the onion and garlic into large pieces and put them in, and remove the oil and foam from them. (3) Boil the soup, remove the meat when the oxtail is rotten, and float the oil floating on it when the soup is cold. (4) Mix beef with seasoning. (5) Cook the soup again, cook the oxtail with seasoning for a while, put it in a bowl, and put the prepared chopped green onion noodles with salt and pepper.
