Dry sea cucumber's soaking method:
1.soak
After cleaning the surface of the sea cucumber, soak it in a clean and oil-free container filled with purified water (the water will not pass through the sea cucumber) for about 24-48 hours, and change the water for 3-4 times until the sea cucumber becomes soft. The purpose of this step is to soak the sea cucumber until it is soft enough to clean the inside.
Step 2 clean
Cut the sea cucumber from the head to the tail along the incision of the abdomen, cut off the sand mouth of the head, remove the teeth of the sea cucumber, clean the impurities in the sea cucumber, and pick off the tendons attached to the inner wall of the sea cucumber. The ribs on the inner wall of sea cucumber contain many nutrients, so don't throw them away.
Step 3 cook in pot
Put the washed sea cucumber into a clean oil-free pot, add purified water, boil over medium heat for 30-60 minutes, do not open the lid after turning off the fire, leave the sea cucumber in the pot and stew until it is naturally cool, pick out the soft sea cucumber, and continue cooking for 5- 10 minutes until it can be pinched thoroughly. You can also put it in a rice cooker, start steaming and cook for 20-30 minutes, and then completely cool it naturally after the cover is turned off (the purpose of this step is to cook the sea cucumber thoroughly).
Step 4 soak
Put the cooked sea cucumber into a clean oil-free container again, filled with pure water, and then put it in the fresh-keeping room of the refrigerator, changing the water once a day, and eating it after 2 days. Sea cucumbers that can't be used up in 3-5 days need to be packaged individually and put in the refrigerator to prevent deterioration. Freezing will slightly affect the taste of sea cucumbers, but it will not affect the nutritional value of sea cucumbers. Frozen sea cucumber should be taken out and put into a container with water to thaw naturally before eating. If it is thawed quickly with hot water, the shape and size of sea cucumber can not be completely restored.
