1, not well soaked, that is, the method of soaking wild dry sea cucumber is wrong. It takes longer for wild dry sea cucumber to soak its hair than for dry sea cucumber.

2. The instant sea cucumber bought is not instant sea cucumber, but half-cooked sea cucumber sold by unscrupulous merchants after scalding fresh sea cucumber with boiling water, mainly for the sake of weight gain and good appearance. If it is cooked well, it will shrink and lose weight.

Solution:

1, clean the sea cucumber, pour it into a clean pot and add water until the sea cucumber is five to ten centimeters.

2. Cook over high heat until the pot is turned to low heat and cooked slowly.

3. Pick up the middle position of the sea cucumber in the pot with clean chopsticks. If the two ends of the sea cucumber hang down about 20 degrees, it is cooked. Take it out, cool it naturally, clean it, put it in pure water and put it in the refrigerator for preservation. Keep cooking what is not cooked, and choose what is cooked while cooking.

4. The boiled and ready-to-eat sea cucumber in the refrigerator is changed with pure water every 12 hours, and it can be soaked in three days.
