First, pour a proper amount of water into the container to clean the dust on the surface of the sea cucumber. Be careful to wash the sea cucumber gently, and don't rub the thorns off the surface of the sea cucumber. Then pour two or three fingers of purified water into the sea cucumber. Cover and soak in the refrigerator 12 hours.

At this time, the sea cucumber has soaked a little. Pour out the water in the container, then pour in fresh purified water and put it in the refrigerator 12 hours. After 24 hours of soaking, the surface of sea cucumber has become a little soft. Cut the mouth of the belly of the sea cucumber with scissors, and then clean the teeth at the top of the sea cucumber.

Then boil a proper amount of boiling water in the pot, add the washed sea cucumber, and continue to cook for about 30 minutes with medium and small fire. After the sea cucumber is cooked, let it cool naturally, then pour in pure water, do not soak the sea cucumber, cover it and put it in the refrigerator for 48 hours, and change the water every 12 hours, so that our dry sea cucumber will be soaked.
