My mother worked in aquatic products company before retirement and was very familiar with the identification and processing of various seafood. After buying empty shells at home several times, my mother told the reason why the empty shells are empty based on her experience:
1. The reason for sorting the snail crabs after they landed
The first sorting of the snail crabs after they landed shore, that is, the fishermen hired people to sort the snail crabs according to their size and fatness. In this way, the sorted snail crabs will be marked with different prices, and the fattest snail crabs will naturally be sold at high prices. This is why the snail crabs in restaurants are basically " top cover fat ".
After sorting, the shuttle crab will be marked with different prices and enter the wholesale market. The vendors will purchase goods according to the different customers they face. Even the crab picker cannot pick out the " top cover fat ".
Buy slut crabs and recognize the principle of " get what you pay for ". It is very important to buy cheap slut crabs, because the price and cost of the vendors are there.
2. Reasons for keeping fresh when selling sling crabs
It is precisely because of modern freshness and fast logistics that sling crabs, such seafood that needs to be eaten while fresh, can be sold all over the country. Even if they are not living in inland areas by the sea, it is not difficult to eat fresh sling crabs now.
Ship crabs need to be given oxygen during the preservation process. After the oxygenation, the spider crabs do not eat for several days, but they can still live well. However, because they have not eaten for several days, the crab meat will decompose. It is not surprising that after buying such spider crabs, they are covered with water after being cooked.
Because the sling crab is marine organism , it is necessary to use seawater to breed during the breeding and preservation process, but the transportation cost of seawater is also relatively high, and ice cubes must be added to ensure the temperature. Those who often visit the seafood market will see cars selling seawater. Buying seawater and adding ice cubes will increase the cost of the sling crab.
Now there is the synthetic sea crystal . Just add a bag to fresh water and it will form a state similar to sea water. This sea crystal is particularly salty. The swift crabs raised with it drink sea water because they are not eaten because they are cooked and they are all water. When they are eaten, they are all salty. The ones we buy are all water. When they are eaten, they are basically spider crabs grown with sea crystals.
When choosing a sling crab, try to choose a sling crab that is not farmed in water, and the sling crab is particularly active, especially a sling crab that can quickly turn over after turning the sling crab. Such a sling crab must be better than that of a sling that will move with its legs.
When choosing a swift crab, if the crab's mouth can spit bubbles, the crab's eyes can move with the fingers. Such swift crabs must be better than swift crabs whose eyes cannot spit bubbles, and their eyes cannot move. This selection method is more useful than pinching the legs and looking at the back cover.
3. The method of steaming crabs is not correct
It is best to insert a chopstick into the crab's mouth before steaming, kill the crab and steam it before steaming, and it is best to turn the abdomen upward when steaming.
If the shuttle crab is steamed alive, it will struggle as the water temperature rises, and it will easily fall off at this time, causing the steam to enter the shuttle crab's body, causing the water inside after the shuttle crab is lifted.
When steaming the swift crab, it is best to boil the water and put it in the pot. This will instantly cause the surface of the swift crab to solidify when heated, so that the water temperature will not increase slowly, resulting in the loss of the swift crab's flavor. Many crustacean seafood steamed in hot water is better than that in cold water.
When steaming a shuttle crab, you can put a piece of ginger on the navel of the crab and drop a few drops of yellow wine in the water, which can effectively remove the fishy smell and increase freshness.
Conclusion:
The best choice for this season of sling crabs is male and second female crabs, that is, those with pointed navel and triangular navel. Such sling crabs are plump than female crabs with round navels. The ones bought by
are all empty-shelled crabs. The main problem lies in sorting, breeding and cooking. As long as you master the identification and cooking methods, it is not difficult to eat " top cover fat ".
