Step 1: soak (48 hours)
Rinse dry sea cucumber with tap water and put it in a clean oil-free container. I use a transparent glass box for easy observation. I poured enough pure water into it, but the sea cucumber didn't eat it.
Then seal the container, put it in the freezer, soak for 24 hours, change the water again, and continue soaking for 24 hours.
wash
Sea cucumber can't be eaten all over the body, and visceral trachoma in abdominal cavity can't be eaten, so this step needs to be taken out and cleaned. Cut the natural cracks in the abdomen of the sea cucumber at both ends with clean scissors, then take out the impurities with clean hands and rinse them clean.
There is no need to remove the internal strength on the abdominal wall. Cut it into 3 or 4 sections with scissors or a knife, which will make the sea cucumber taste better after soaking. Finally, rinse the processed sea cucumber with pure water, and then proceed to the next step? Boiled ginseng? Yes
cook
This step is crucial, and whether the sea cucumber can be delivered in place depends on this step.
Put the sea cucumber into a clean oil-free pot, add purified water, which needs more water than the sea cucumber, to prevent the water from being boiled dry, and cover the pot. Then follow these steps:
(1) Bring boiling water to a high fire, then simmer for 20 minutes, then turn off the fire and stew for 30 minutes.
(2) Continue to simmer for 20 minutes, then turn off the fire and stew for 25 minutes.
(3) Then check the sea cucumbers one by one, and the cooked sea cucumbers can be easily pinched and presented by hand? Chopsticks are in the middle, two.
The head bends naturally? State of
(4) Pick out the cooked sea cucumbers, put them aside, and continue to cook the uncooked sea cucumbers (the cooking time depends on the sea cucumbers).
Shorten it appropriately) until every sea cucumber is pinched thoroughly.
The first time I cooked sea cucumber was in the afternoon 10. Although it didn't take long to cook, I ignored the natural cooling time of the water in the pot and basically didn't sleep all night. By the time the pot cooled down for the second time, it was already 6 o'clock in the morning.
The sea cucumber cooked in this way will gain weight obviously. The basis for judging whether the sea cucumber is cooked or not: when it is picked up from the middle, the head and tail will droop slightly, that is, it is cooked, and then it will enter the final soaking stage.
Step 4: soak (24-48 hours)
This step is basically the same as the first step. Put the cooked sea cucumber in a clean oil-free container, pour enough pure water, seal it and put it in the refrigerator.
However, in this link, the sea cucumber will obviously become bigger, and more water must be added to prevent the sea cucumber from absorbing all the water.
If it is a relatively small sea cucumber, it can be completed by soaking for 24 hours; If it is a big sea cucumber, soak it in pure water for 24 hours and then soak it for 24 hours, and you're done!
It really surprised me that the humble San dry sea cucumber was sent such a big size. Completely different from the original imitation? Ginseng? .
The length is basically 2-3 times of the original, and the weight of water-saturated sea cucumber is more than 12 times of the original. Sea cucumbers can be delivered more than once, and those that are not eaten for the time being can be packaged separately and placed in the frozen layer of the refrigerator.
The second production method
1, immersion desalination
Rinse dry sea cucumber slightly, put it in an oil-free clean container, pour enough purified water and start foaming.
Soak for more than 24 hours, and change the water once every 6-8 hours until the sea cucumber swells, and it is no longer hard and elastic to pinch and can be bent at a large angle.
2. Go to the mouth and break the tendons
Cut the whole abdomen along the small hole at the bottom of the sea cucumber, turn around and cut the white tendon on the inner wall of the sea cucumber into sections.
This will make it bigger, otherwise it will limit the foaming rate, but don't throw it away because? One flower, two tendons and three rolls? White tendons are also very nutritious parts.
3, boiled
Put the cleaned sea cucumber into an oil-free pot with good heat preservation performance (an ordinary pot is ok, but it must be oil-free).
Pour enough pure water, and the water should not exceed 5- 10 cm of sea cucumber. After boiling over medium heat, turn to low heat and simmer for 30-50 minutes. Stir several times during the boiling process to prevent the pan from sticking.
4. Simmer and cool thoroughly.
Turn off the fire after cooking, do not lift the lid and continue to stew until it is naturally cool. The standard of stew is to put the sea cucumber in the middle, and the two ends will naturally droop slightly. When you hold the sea cucumber, it will shake slightly, and you can easily pass through the skin and meat of the sea cucumber.
The uncooked sea cucumber can be cooked for a second time in the same way as above. This step determines the final taste of sea cucumber.
5. Ice blisters
Continue to put the braised sea cucumber in an oil-free container, pour enough pure water and ice cubes, cover it, and put it in the refrigerator for refrigeration. You can eat it in 2-3 days.
Among them, it takes 6-8 hours to change pure water and ice cubes, and the water should not exceed 5- 10 cm of sea cucumber. The purpose of ice blisters is to make sea cucumbers rise better. Sea cucumber will shrink and swell when it is cold, and its taste will be better.
6. Frozen storage
If you don't eat the prepared sea cucumber for the time being, wrap it tightly with plastic wrap and put it in the refrigerator for frozen preservation. Thaw naturally at room temperature before eating.
Nutritional value of sea cucumber
Modern scientific research has proved that the nutritional value of sea cucumber is high. Every hundred grams contains more than 50 kinds of nutrients beneficial to human physiological activities, such as protein 15g, fat 1g, carbohydrate 0.4g, calcium 357mg, phosphorus 12mg, iron 2.4mg, vitamin B 1, B2, nicotinic acid, etc.
Among them, the content of protein is more than 55%, and there are 18 kinds of amino acids, taurine, chondroitin sulfate and sea cucumber mucopolysaccharide. Arginine is the main component of male sperm cells and the main raw material for synthesizing human collagen, which can promote the regeneration of body cells and the repair of damaged bodies, improve human immune function, prolong life and eliminate fatigue.
Sea cucumber is a typical high-protein, low-fat and low-cholesterol food with extremely low cholesterol. Because the meat is tender and easy to digest, it is very suitable for the elderly, children and the weak.
Taurine and nicotinic acid in sea cucumber have the functions of regulating nervous system, quickly eliminating fatigue and preventing skin aging.
In addition, taurine, lysine and methionine contained in sea cucumber are almost absent in plant foods. Pharmacological experiments have proved that chondroitin sulfate and sea cucumber mucopolysaccharide contained in sea cucumber have special effects on human growth and development, anti-inflammatory osteogenesis, prevention of tissue aging, promotion of wound healing and inhibition of several cancer cells.
