Usually, the sea cucumber is soaked to make it grow big and beautiful, and it will be soaked for several days. After the sea cucumber is cooked, the sea cucumber grows, but the part that grows is the water absorbed by the sea cucumber. Therefore, after encountering high temperature heating, the water comes out and the sea cucumber shrinks.

If you want the prepared sea cucumber not to shrink, you can freeze it with warm water or cold water when you freeze it. When you eat it, don't put the sea cucumber in the pot for a long time. You can eat it by scalding it with hot water. When you make soup or porridge, you need to add the sea cucumber 1-2 minutes before you take it out.
