First take out the frozen clam meat and thaw it in the microwave oven. After thawing, we should pour it into a basin, soak it in water and some salt for about 30 minutes, then pour out the water, pour out the water, and then we will put the clam meat. Black or brown intestines, especially the dark parts above, are removed by hand, leaving only white or flesh-colored and light-colored mussels. Pick them all out and wash them in a basin for about three or four times. After cleaning, as long as the moisture is well controlled, the black things on the frozen clam meat will be thoroughly cleaned.

The black color in clam meat is: mud in the sea or excrement of clams, internal organs of clams, and excrement of clams if it smells bad. Meretrix meretrix (little seafood) is small in size, so the organs gather, and the internal organs, stomach and excreta can basically be regarded as piled together, so it is impossible to separate them. Because clams are too small to open easily, there will always be a lot of fine sand to take away. Fine sand is harmful to gastric mucosa, and excrement also contains bacteria. This truth is just like animal manure can be put in the ground as fertilizer, and eating too much can also have disadvantages. There may be sediment residue inside and outside the clam shell, which will affect the taste if it is not cleaned. If you eat sediment when drinking mustard soup, you will definitely feel uncomfortable, so wash the clams before cooking.

How to remove the black things from fresh clams: We put fresh clams in water, add some edible salt and a few drops of sesame oil, and soak them in water for about two hours, so that Gree can spit out the sand in his body. When the time is up, rinse it twice with clear water, put water in the pot and soak the clams in the pot. Until every clam opens its mouth, turns off the fire and removes the floating foam. Then take it out and clean it with clean water.

Then one by one, he peeled off its shell and put the clam meat in it. Take it out gently. Then take out the black intestines like shrimp lines in the prawns. Or like brown or dark oranges, take them out and wash them with water. After cleaning, dry it, put it in a fresh-keeping bag, freeze it, and then take it out for use when cooking soup or stir-frying.
