There are two ways to eat crabs. After freezing, the meat will become softer, the taste will deteriorate, and the freshness will be different, and it will definitely not work to steam it directly. For this type of crab, the general practice is to first marinate the crab, cut it into pieces, remove the gills and tips, sandbags, then put it in a container, tidy it up, sprinkle it with salt.
The amount of salt in each layer depends on the taste. However, there must be a certain amount, otherwise it will be undercooked. The criterion for undercooked meat is whether the meat is detached from the shell.
If you feel too fishy, you can put some ginger slices and two tofu crab soup (personal favorite), thaw the crab, cut it into pieces, remove the gills, remove the sandbag, remove the tip, and put it in water to boil. Once the color of the soup has changed basically, add the lactone tofu (cut into cubes) and cook for 5 minutes. The general ratio is 1 box of tofu and 2-3 medium crabs.
Third, fry the crab in scallion oil, cut it into pieces, remove it three times (as mentioned above), dry it, heat it, put the bottom oil, cover the bottom of the pot, wait for the oil to smoke, add salt and ginger shreds (fragrant and fishy), after 10 seconds, put in the crab pieces, stir-fry constantly, after the color of the crab shell changes, put a little soy sauce (I like soy sauce to look good.)
