1. Remove the salt on the surface of sea cucumber with clear water, and then pour a proper amount of purified water into a clean and oil-free container. Put the sea cucumber in a container and put it in the refrigerator for 24 to 48 hours. Change the water every 8 hours until it becomes soft.

2. Cut the soaked sea cucumber to the head along the midline of the abdomen, take out the sand mouth and inner ribs, and then clean up the impurities in the sea cucumber belly together. The tendon in the cavity of sea cucumber is edible, and it can be removed, but it will have a certain impact on the size of the soaked sea cucumber, so it is good to cut several sections inside.

3. Put the purified water into a clean oil-free pot, and then put the washed sea cucumber into it. After the sea cucumber is boiled with strong fire, turn to low heat and cook for 20 minutes. After turning off the fire, you don't need to uncover the cover, just cover it until the sea cucumber is naturally cool, and then take out the boiled sea cucumber. Leave the hard sea cucumber in the pot and cook it again with clear water until one is completely soft.

4. Put the cooked sea cucumber in a clean, oil-free container, fill it with cold water and seal it, then put it in the refrigerator, continue to soak for 48 to 72 hours, change the water once a day and eat it at any time.
