There is not enough time to cook. Cooked pigskin can be frozen because it is rich in collagen, boiled in boiling water, converted into gelatin, and then swollen into gel in water at 35-40℃. After cooling, the gel tightly freezes the skin. But the boiling time is not enough, which leads to the final swelling of the gel, which is not enough to solidify the jelly. The ratio of too much boiling water to pigskin is too large, and too much water causes the gel to swell, which is not enough to solidify the cooked solution.

Curing temperature and time, skin freezing needs certain time and temperature conditions, generally at room temperature, it takes overnight or 12 hours to fully form. Too much water leads to non-solidification, so it needs to be boiled again, and the amount of water is moderate. If it doesn't solidify because the cooking time is too short, it should be cooked again. If the fat (oil) on the skin is not scraped clean, you can cook another pot. Scrape off the pigskin you bought (about cm thick, try to scrape off the grease).

Wash the pigskin, boil it for 2 minutes, and then soak it in ice water for 20 minutes while it is hot. Cut the processed pigskin into vegetables, add 1 times of water to the cut pigskin, exhale at high pressure, and turn to low heat for 45-60 minutes (remember to put an octagonal and take it out after cooking). Put the cooked meat and skin soup into a container and refrigerate overnight. The water must be moderate. You can put more water first, and then cook it to a moderate degree. Add enough water, about 3 liters of water, to the pot until the remaining amount can be poured into a container containing 1 kg of pigskin. This will fully cook pigskin and pigskin jelly, which will be more successful.

Pigskin jelly is a very delicious food. Pigskin jelly contains a variety of protein and can be eaten in a variety of ways. What's wrong with it? Frozen pigskin jelly is amorphous because of its short freezing time and can be frozen for a longer time. Put the frozen pigskin into a bowl, then wash the cucumber, peel it, shred it and put it on a plate. Add sesame juice and sauce, stir well, and you can make delicious cold noodles and eat them directly. It can also be eaten with various staple foods. You can also mix cold pigskin jelly.
