1. After you buy fresh sea cucumber, you must break your belly and remove the dirt in time, otherwise the sea cucumber will soon lose weight and even dissolve into liquid. The method is very simple, that is, cut open the belly of fresh sea cucumber, remove the intestines and stomach inside, then wash it with washing water, and then remove the mouth of sea cucumber.
2. Boil the washed sea cucumber in boiling water for about 45 minutes. Boil the sea cucumber until it shrinks and feels elastic by hand. This step can also be done by steaming the washed sea cucumber in a pressure cooker for about 30 minutes.
3. Boil the sea cucumber in rice washing water for 1 ~ 2 hours, and take it out when it is tender.
4. Wash the sea cucumber with cold water and soak it in pure water or cold water. It usually takes two days to soak, and pay attention to changing the water several times in the middle. If you soak in the fresh-keeping room of the refrigerator, you can change the water a few times less.
After soaking for two days, you will find that the sea cucumber is much bigger and softer than when it was just cooked, and it can be used to make all kinds of delicious food.
6. If the processed sea cucumbers can't be eaten all at once, each sea cucumber can be packaged separately in a small plastic bag and placed in the freezer of the refrigerator. When eating, you only need to melt the sea cucumber with water, and you can eat it at will, and it is best to take one tablet a day.
The selection of fresh sea cucumber mainly depends on whether there is peeling phenomenon, that is, whether the surface of sea cucumber is festering or not, and the thickness of sea cucumber epidermis (although fresh sea cucumber is big and good, it may be big because of too much water, so choose carefully). The thicker the skin, the closer you touch it, the better, indicating that it will last for a long time, and the wild one is better than the captive one. Wild Stichopus japonicus is dark brown in appearance, rod-shaped, with 4-6 rows of thorns, and the thorns are neat. Sea cucumber has thick cortex, high collagen content and dense tissue.
