In two ways:
First, the hot bubble method first soaks the sea cucumber in hot water for 24 hours (you can directly put it in a pot and boil it in cold water, then cover it and stew it for 4-5 hours), then take out the internal organs from the lower mouth of the abdomen, add new water, cook it for about 50 minutes with strong fire, and soak it in the original soup. After 24 hours,
The second is the cold water foaming method, that is, the sea cucumber is soaked in clear water for about 3 days; Take out the intestinal impurities and peritoneum by laparotomy, and then soak them in clear water until they are soft before processing and eating. This method needs to change the water several times in hot weather, and always pay attention to whether it softens.
When soaking sea cucumbers, don't be contaminated with oil, alkali and salt, otherwise it will hinder the water absorption and expansion of sea cucumbers, reduce the yield, and even make sea cucumbers melt, rot and deteriorate. The prepared sea cucumber can't be frozen, otherwise it will affect the quality of sea cucumber, and it is not advisable to send too much at a time.
