Can crabs be frozen again after steaming for a few days?
Yes, but it needs specific analysis.

If you put it in the refrigerator or at room temperature, the meat will dry easily, but if you reheat it, it will have a special taste, so it is best to eat a few pieces each time you cook, and everyone should try not to leave any. If you want to eat, try to steam it back to the pot before eating, but cover it in the frozen (non-refrigerated) layer of the refrigerator. Because the cooked crab is toxic after contact with fog and dew, it must be cooked again the next day, boiled in boiling water, and heated for half an hour after boiling to prevent the microorganisms in the crab from being completely killed. Avoid eating crabs without seasoning, because they are cold. When eating crabs, add Jiang Mo and vinegar to prevent stomach injury.

Extended data

Generally, the crabs we eat are divided into sea crabs and river crabs.

Sea crabs include swimming crabs and blue crabs. Because of the transportation mode, meat quality and other factors, this kind of crab is frozen for sale, which means that most of the sea crabs we bought are frozen, and this kind of frozen crab is no problem.

River crabs, commonly known as "hairy crabs", are generally eaten fresh, and the hairy crabs sold in the market are all fresh. Living hairy crabs can be stored in the freezer, but it is not recommended.

What method is feasible to preserve hairy crabs? .

Don't wash crabs, and don't untie the rope that binds them. Put the crab directly into the freezer and adjust the temperature to 5-8 degrees Celsius. Then, put a wet towel on the crab's back. The humidity of the towel is about the humidity when you wipe your face.

Preserved in this way, crabs can enter a state similar to "dormancy" in the refrigerator and can last for about 5 days without dying. In this way, when we cook, we can keep the delicious taste of crabs to the greatest extent.

What if it must be stored for a long time?

If you need to store hairy crabs for a long time, you can only put them in the freezer of the refrigerator. Hairy crabs can be stored for 1-2 months in the frozen state. But it should be noted that crabs must be frozen while alive. If the crab dies, you can only throw it away with regret. After death, crabs will produce a toxic substance called "histamine", which is seriously harmful to health, so they can't eat any more.

How to "rescue" frozen crabs?

The taste and taste of frozen crabs are definitely not as good as those of fresh crabs. For frozen crabs, I suggest you do this:

Thaw. Don't let crabs thaw naturally, it's better to thaw them with salt water. Putting salt in the water can speed up the thawing, and can play a role in sterilization. Pay attention to cooking immediately after thawing to minimize the exposure time of crabs in the air.

Become suspicious. Frozen crabs will smell worse than fresh crabs. Therefore, I suggest to choose the cooking method of boiling water. In the process of boiling crabs, you can put more perilla, ginger slices and cooking wine in the water, which can remove the fishy smell to some extent.

Time. Whether steamed or boiled, the cooking time is very important. If cooked for too long, crab meat will get old easily. However, for frozen crabs, it is better to cook them for a while, so as not to cook them inside, causing gastrointestinal discomfort.
