Can frozen swimming crabs be eaten?
Frozen Portunus trituberculatus is edible, but its taste is definitely not as good as fresh one, and its practice is different from fresh one.
After freezing, the crab meat will become soft, the taste will become worse, and there will be a gap in umami, so direct steaming is definitely not acceptable.
How to make frozen swimming crabs?
First marinate crabs, cut into pieces, remove gills and sharp parts, and sand bags, then put them in containers, arrange them, sprinkle salt, and salt crabs one layer at a time. The amount of salt depends on the taste. But there must be a certain amount, otherwise it will not be cooked. The standard of cooked and uncooked is whether the meat is separated from the shell.
If it is too fishy, you can put some ginger slices.
The second tofu crab soup (personal favorite), thaw the crab, cut into pieces, remove the gills and gizzards, remove the sharp parts, put it in water and cook. After the color of the soup changes basically, add lactone tofu (cut into pieces), boil for 5 minutes, thicken the powder and take off the pot. General collocation
The ratio is 1 box of tofu, 2-3 medium crabs.
Third, fry the crab in scallion oil, cut the thawed crab into pieces, remove it three times (as explained above), dry it, heat the pot, put the base oil all over the bottom of the pot, add salt and shredded ginger (to remove fishy smell), 10 second later, add the crab pieces, stir fry continuously, and add a little soy sauce after the color of the crab shell changes.
Preservation skills of Portunus trituberculatus
Put it in a clean container, mix two broken eggs with brown rice, sprinkle some black sesame seeds, pour this mixture into the container to drown the crab's shell, and then cover the container with a dark cloth, which should be breathable but not light-tight. This can prolong the survival time of crabs and make the taste of sea crabs fatter and fresher.
If you don't want to go to so much trouble, you can also put the sea crabs directly in a basin with a little shallow water, add a breathable cover, or tie the crab legs, otherwise they will crawl away.
If it is chilled sea crab, it can be stored in the freezer for about 1-3 months. But be careful not to unfreeze again.
