Generally speaking, dried fish glue can be divided into new glue and old glue. The effect of old glue is better than that of new glue, because old glue is easy to absorb, and new glue and fresh fish glue are not easy to absorb. Although I eat it, I really absorb very little. Like chicken wings with pig's trotters, it feels delicious, but compared with fish glue, the absorption degree is much worse.
