How to make jelly:

1. First, clean the skin, and the most important thing is to remove the hair from the skin, so that the taste will be good. After that, add water to the pot. After the water boils, put the skin in the pot and cook it for a while, then take it out. When it is not hot, cut off the oil on the skin with a knife, and then wash it with water. Finally, cut the washed skin into small strips and put them in a clean pot, and add more than half of the water (if you want pure white crystal jelly, you don't need to put any seasoning, but you can put some cooking wine properly to get rid of fishy smell; If you want to look at the color, add some soy sauce to the pot, so that it will be slightly sauce-colored, and the dish will look better. Then, after the fire is boiled, cook it on medium and small fire until the soup is thick, that is, turn off the fire after the water is almost half, cool it and pour it into the container and put it in the refrigerator. After the skin jelly is completely formed, you can change the knife to serve. 2. Before eating, it is best to sprinkle some shredded garlic or coriander on it (I don't have garlic or coriander at home today, so I use celery leaves to match the color temporarily) 3. Pour the prepared soup (the soup is made with a little soy sauce, vinegar and sesame oil), which is delicious.
