First, put pure water in an oil-free container (water should not pass through the sea cucumber) and soak it for about 24-48 hours. Change the water once every 8 hours and 3-4 times until the sea cucumber becomes soft.

Then cut the sea cucumber from beginning to end along the incision in the abdomen, cut off the sand mouth of the head, remove the teeth of the sea cucumber, clean the impurities inside the sea cucumber, and pick off the tendons attached to the inner wall of the sea cucumber.

Oil-free sea cucumber is easily put into purified water and boiled for 40-60 minutes. Don't open the lid after the flameout. Leave the sea cucumber in the pot to cool naturally, pick out the soft sea cucumber, leave the hard sea cucumber or sea cucumber with hard core in the pot, and continue to cook with pure water until it is completely soft and cooked.

Finally, put the cooked sea cucumber in a clean and oil-free container again, fill it with purified water, then put it in the fresh-keeping room of the refrigerator (the purified water will expand more after soaking with some ice cubes, and the taste will be better), then soak it for about 24-48 hours, and change the water for 3-4 times, so that it can be eaten.

After doing this, you can eat delicious sea cucumbers. I hope you are satisfied with the answer of the champion sea!
