working methods

1. Wash the chopped bones, put them in a soup pot (casserole is best), add water, cover the pot, and boil over high heat.

2. When cooking, peel the lotus root and wash it, cut it into pieces about half a centimeter thick, slice the ginger, and wash the medlar and kelp.

3. After the water is boiled, skim off the foam and cook at the edge of the water until there is not much foam in the soup.

4. Add ginger, lotus root and a few drops of white vinegar. When the soup boils again, cook it over low heat. You can cook other dishes at this time.

5. After one and a half hours, put the kelp knots and medlar into the soup and continue to cook for about half an hour on low heat.

6. Sprinkle the right amount of salt.
