If you use a pressure cooker, it will be less than two kilograms. The iron pot is less than the pressure cooker, but you should see the amount of water. One kilogram of pigskin and three kilograms of water are a good ratio. If the proportion is not well mastered and the pigskin is not hard, you can keep it longer.

The ratio of pigskin to water is about 1 kg pigskin and 3 kg water. If the proportion is not well mastered and the pigskin is not frozen hard, you can cook it for a while as appropriate.

1, cut the skin into 6-7cm strips. Put it in a pot, add water until it overflows the epidermis, heat it until the water boils, then turn off the fire and stew for 10 minutes.

2. Scrape off the oil on the inside of the skin and scrape off the old skin on the outside. Cut the scraped skin into 2-3 mm strips, add 2-3 spoonfuls of salt and appropriate amount of water to the basin.

3. Grasp it with gloves for 2-3 minutes, and then rinse it with clear water (it is recommended to rinse it for more than 4 times). The purpose of this step is to remove the fat and old skin attached to the skin surface.

4. Add water to the skin and put it in the steamer 100 minutes. The ratio of adding water to the skin is as follows: 1 kg of raw skin can be made into 1.2 kg of cooked skin, and water is added to 1280 ml.

5. After steaming, filter the skin. When the temperature of the soup is slightly cool, put it in the refrigerator or cool it at low temperature.

6. Take the frozen jelly out of the refrigerator when eating. According to personal taste, with soy sauce, vinegar, garlic and so on, it becomes a delicious crystal jelly.
