Precautions for soaking sea cucumbers

1. Pure water must be used for foaming

Foaming sea cucumbers has very high requirements for water quality. The effect is best. The softness and hardness of tap water vary from place to place. Mineral water generally contains more calcium, magnesium and other minerals and has a certain hardness, so it is not the best choice for foaming sea cucumbers, especially when it is boiled. It will cause rust, so be sure to use pure water.

2. The waterproof temperature is too high

Careful sweet potatoes will find that the high temperature of the water used to soak sea cucumbers will promote the molting of sea cucumbers, which is the beginning of autolysis. Do not soak sea cucumbers at room temperature, as this will easily cause the skin and residue to peel off. In addition to the 1-2 hours that must be cooked for the soaking process, you must pay attention to the temperature when soaking sea cucumbers. It is recommended to maintain a water temperature of 0-5℃. Putting it in the fresh-keeping layer of the refrigerator is the best choice for sweet potatoes.

3. Oil-proof

Be sure to prevent oil when drying sea cucumbers. This is because after dry sea cucumbers absorb water, there are irregular pores on the surface. If oil adheres to the surface, the pores will be blocked. If it is blocked, the water flow inside and outside the sea cucumber will be affected, and the epidermis will easily fall off. This will not only affect the effect of sea cucumber foaming, but also cause the loss of sea cucumber nutrients. Therefore, foaming sea cucumbers must be oil-proof.

4. Salt prevention

The protein content in sea cucumbers is very high. If the protein encounters salt, it will easily shrink and solidify, causing the sea cucumbers to be soaked. Therefore, foamed sea cucumbers must be salt-proof.

5. Alkali resistance

The fat of sea cucumbers is collagen protein. When this protein encounters alkali, it will corrode the fat of sea cucumbers and the sea cucumbers will rot. Therefore, foaming must be resistant to alkali. How to foam dried sea cucumbers? Step 1: Dried sea cucumbers are relatively hard and need to be soaked first. Wash the dried sea cucumbers and put them into a clean, oil-free container. Pour in pure water to completely soak the sea cucumbers, and then place them in the refrigerator's fresh-keeping layer. , soak for about 36-48 hours, and change the water every 8 hours or so until the sea cucumber is soaked soft. The second step is to go to the sand spit. Take the sea cucumber out of the refrigerator. There is a small opening in the belly of the sea cucumber. Use scissors to cut it lengthwise along the small opening. You will see that one end of the sea cucumber has teeth, which are small white particles that feel hard to the touch. , remove the tooth. Keep the inner tendons of the sea cucumber. You can cut or not cut the inner tendons. Cutting will make the hair bigger. The third step is to cook in the pot (the key step for success or failure): This step is the most critical. Add pure water without oil to the pot, put the sea cucumber in cold water into the pot, bring to a boil over high heat, then lower the heat and simmer for about 30-60 minutes. The specific situation of each sea cucumber is different. You should observe it frequently. Use chopsticks to hold the sea cucumber in the middle and the two ends will naturally droop. This means that the sea cucumber has been heated enough. The cooked sea cucumbers should be taken out at any time. If the sea cucumber is hard, continue to cook until it is cooked. soft. The simplest way to check the heat of sea cucumbers: use chopsticks to pick up the sea cucumbers after cooking. If it is easy to pick up, it means it needs to be cooked again. If it is difficult to pick up, it means the cooking heat is about the same. If it cannot be picked up, it means it is overcooked. Fish it out quickly.

The fourth step is to soak in purified water. The amount of water should not cover the sea cucumbers (purified water must be used). Bottled purified water or water purchased in supermarkets can be used. Put it in the fresh-keeping layer of the refrigerator to soak for about 36-48 hours. , change the water every 12 hours. Every time you change the water, you will find that the sea cucumber magically gets bigger.
