The ingredients used to make pork bone soup are: straight bones, fan bones, tail bones, broken bones, onion knots, ginger, and wine.

After buying the bones, wash them with warm water, because the grease cannot be washed away in cold water. Soak it in water again, the water will turn red, and then change the water twice.

Cold water should be used to stew pork bone soup. Because there is always a little meat on the general meat bones, if hot water or boiling water is poured into the pot at the beginning, and the surface of the meat is suddenly exposed to high temperature, the outer protein of the meat will solidify immediately, so that the protein in the inner layer cannot be fully absorbed. Dissolve into soup. Only by adding enough cold water at one time and heating it slowly can the protein be fully dissolved into the soup and the soup will taste more delicious.
