If you don’t use pork skin, you can only use edible glue. I’ve seen people make plain jelly, cut very fine carrot shreds, minced coriander, dried tofu shreds, and then add water, salt and MSG to the edible glue. When the aniseed is boiled, use a special plastic casing to tie it up with a rope. Put the individual shreds into the casing, then pour the boiled water into it, tie it up, and put it in cold water. Turn it from time to time, otherwise the material inside will be uneven. , and then it condenses into skin jelly.
