You can use the quick freezing method by adding water.

If you want to ensure the perfect taste of fresh swimming crabs, it is best to choose the quick-frozen method of adding water. The method is very simple, prepare a small box, stack the swimming crabs one by one (you can tie the crab legs in advance), then add water into it until the water completely covers the swimming crabs, cover it and put it in the freezer of the refrigerator to freeze. .

Take it out and defrost it before eating, and cook it according to your favorite method. This method is currently used for long-distance transportation and sales, which can ensure the freshness of swimming crabs to the greatest extent without affecting the taste of the meat. "Frozen" swimming crabs are not suitable for steaming and are best eaten fried.

Notes on steaming swimming crabs:

1. Select swimming crabs: Dead swimming crabs are particularly cheap. Some people buy dead swimming crabs in order to save money. This is wrong. Eating seafood means eating "fresh". Only live ones are fresh. Dead ones are not only not fresh, but can also produce bacteria and harm your health. Male crabs have crab paste and female crabs have crab roe, both of which taste delicious. Male crabs have pointed navels, while female crabs have round navels.

2. Prevent swimming crabs from struggling to lose their legs: Put live swimming crabs into the steamer, no matter whether the navel is facing up or down. After being heated, it will struggle to kick off its legs, causing the legs to fall off and the fishy smell will be strong. Therefore, the crabs must not move after being put into the pot. There are three methods:

①Tie the swimming crabs up like hairy crabs;

②Soak the swimming crabs in wine for a while and make them drunk.

③ Kill the swimming crab before steaming it. You can use chopsticks to penetrate from the mouth of the crab to the heart of the crab, and the swimming crab will be dead. Steaming them immediately after being stabbed is not only easy to clean, but also tastes as delicious as live crabs, which is different from buying dead crabs directly.

3. How to remove the fishy smell: Aquatic animals are basically cold in nature, so ginger should be used to remove the fishy smell for the best effect. Ginger is warm in nature, which can neutralize the cold nature of swimming crabs, and can also remove the fishy smell and increase the fragrance. Three points need to be noted:

① Put ginger in the water;

② Place the swimming crab belly button up on the ginger slices, and put another piece of ginger on the belly button. No yellowing;

③When making sauce, you should also add some minced ginger.

4. How long to steam: If you want the crab meat of the swimming crab to be plump and firm, how long to steam is also critical. If the time is short, it will not be cooked, and if the time is long, it will be cooked. The old fisherman said that the length of steaming depends on the size of the swimming crab. After the water is boiled, steam for 10 minutes for items of 150 grams and below, 12 minutes for items between 150 and 200 grams, and 15 minutes for items over 200 grams. For every additional tael in size, steam for 2 more minutes. Although swimming crabs cannot be steamed, they must be steamed thoroughly to kill bacteria, germs, parasites and other harmful substances in the body.
