1. If the amount of water is too much and it does not solidify, it should be returned to the pot and simmered again. When the amount of water is appropriate, start the pot again. If it does not solidify because the cooking time is too short, it should be boiled again. If the fat (oil) on the skin of the meat is not shaved off, you can cook it in another pot.

2. Pig skin jelly is a traditional delicacy made from pig skin. Add appropriate seasonings to the pig skin with the hair removed, and simmer it for a long time so that the soup contains a certain amount of skin glue, and then cool it. After cooling, the pig skin and the soup will solidify together, and the soup will be dipped in it. Add seasoning and serve. Because it is eaten after cooling, cooling can be said to be freezing, so it is called pig skin jelly.
