1. How to clean frozen sea cucumbers

Prepare ingredients: 4 frozen sea cucumbers, appropriate amount of purified water

1. First, place the frozen sea cucumber in a container, pour in pure water to thaw and soak for 48 hours.

2. Take out the sea cucumber after 48 hours and cut it from the mouth along the belly.

3. Rinse off the mud and sand in the sea cucumber's belly and remove the tendons in the sea cucumber's belly.

4. Cut off the teeth and mouth of the sea cucumber and discard them.

5. Put purified water and washed sea cucumbers into the pot.

6. After boiling over high heat, turn to low heat and cook the sea cucumber for half an hour.

7. Turn off the heat after half an hour and simmer the sea cucumber for 2 hours.

8. After 2 hours, remove the sea cucumber and soak it in pure water for 48 hours.

9. After the sea cucumber and celery are soaked, they can be cooked directly.

1. Frozen sea cucumbers have been soaked in water and will not shrink.

2. Soak in water until the smell of seawater disappears and then rinse. This takes about half a day.

3. Pick it up in boiling water to remove the fishy smell.

4. I don't know what kind of braised pork skin you are talking about. If it is braised pork, just slice it and stir-fry it; if it is the same as fried pork skin, yellow and foamy, you have to fry it in a pan. Generally, this is not done.

5. When frying, fry the sea cucumber in the pan first, then add the other ingredients. This way it will be chewy and tough. If it is too tender, it will be like fish jelly and too soft.

6. Stir-fry over high heat.

7. In fact, the best and most nutritious way to eat sea cucumbers is to stew them into soup with more ingredients. Sea cucumbers themselves have no taste, so you just eat them for their nutrition; the taste depends entirely on the ingredients.

2. How do sea cucumbers defend themselves against enemies?

There is a special organ in the sea cucumber that contains toxins - the Cuvierian tubule. When invaded by the "enemy", it can discharge the Cuvierian tubule from the anus to entangle and poison the invading "enemy".

In addition, sea cucumbers have a special way to defend themselves from enemies, which is to use the strong contraction of muscles to expel their internal organs from the anus to confuse the enemy and take the opportunity to escape. Interestingly, the enemy often only swallows the internal organs of the sea cucumber and does not eat its body wall. Why is this? It turns out that the body wall of most sea cucumbers contains sea cucumber toxins, which can cause toxic reactions in the swallower, causing symptoms such as muscle paralysis and hemolysis.

Sea cucumbers have a strong regenerative ability, and expelling their internal organs does not endanger their lives. After 1 to 2 days, a new set of internal organs will form in their bodies.

3. How to kill live sea cucumbers

Use a knife to cut the sea cucumber longitudinally in the middle of its abdomen (the side without spines), cut out about half of its total length, and remove its internal organs. Also, there is a sand mouth (something like teeth) at the front of the sea cucumber, just remove it.

4. How to kill live sea cucumbers…………

The purpose of the initial cooking of live sea cucumbers is to first remove the strong fishy and astringent smell of live sea cucumbers and highlight their freshness. Secondly, it is to grasp the texture of live sea cucumbers. If the heat is too high, the sea cucumbers will be as hard to chew as rubber strips, and will be shrunken and dull. If the heat is not enough, the texture of the live sea cucumbers will not be soft and tender, and the effect is not ideal. Below is a comparative introduction to the two initial cooking methods of live sea cucumbers.

The first method: blanch the whole live sea cucumber in boiling rice water, quickly remove it, rinse it with clean water, cut open the abdomen, remove the sea cucumber's internal organs, and clean them with water. Put the second rice water into the pot, add the sea cucumber and boil it, steam it on low heat for about four or five minutes, remove it and drain the water, then you can cook the dish directly.

Notes: ① It is necessary to cook it with rice water to soften the sea cucumber meat and remove the fishy smell of the sea cucumber, making it fragrant when cooked. ② After the live sea cucumber is cooked, it should be allowed to cool slowly before cutting it into shape. ③ The live sea cucumber processed in this way is generally suitable for making cold dishes (such as mixing, sautéing, and drunken cooking techniques). Its representative dishes include cold-mixed live sea cucumbers, sautéed golden live sea cucumbers, drunken live sea cucumbers, etc. ④ The advantage of this method is that it is easy to process and the heat is easy to control. The disadvantage is that the taste of live sea cucumbers is relatively simple, so you need to pay attention when seasoning.

The second method: Beat the live sea cucumber with egg white and sugar for a few minutes, then wash it with clean water, put it in a pressure cooker, add broth, star anise, onion, and ginger slices, boil it, and heat it for about 10 minutes. Take out the live sea cucumber and soak it in hot alkaline water for about 4 hours, then take it out, rinse the alkaline water with clean water, then put it in pure water, refrigerate it in the refrigerator for about 5 hours, take out the sea cucumber, open it, remove the internal organs, blanch it in boiling water, take it out, and cut it into shape.

Notes: ① Live sea cucumbers processed in this way are suitable for hot dishes, generally using techniques such as roasting, frying, and boiling. Representative dishes include: scallion-fried live sea cucumbers, braised live sea cucumbers, etc. ② Mastering the length of time the live sea cucumbers are heated in a pressure cooker is the key to the success of this method. ③ Live sea cucumbers processed in this way should be processed and cooked immediately. Do not store the processed live sea cucumbers for a long time, otherwise the live sea cucumbers will easily become dehydrated and rot, resulting in waste.
