To remove the sand from the quick-frozen clam, first pour an appropriate amount of water into the pot and heat it to boiling, and then pour the quick-frozen clam into the pot and boil it until the water in the pot boils again. At this time, almost all the shells of the clam are opened, and we can clean the sand in it with a brush.
Usually, the quick-frozen clam has died. It can't open its shell by itself, so the traditional method of soaking in salt water doesn't work for this kind of clam.
If we want to sand the quick-frozen clams, we should first prepare a pot of water and heat it to boiling, and then pour the quick-frozen clams into the boiling water. After the water in the pot boils again, we will take out the clams. At this time, most of the clams' shells should be opened.
Then we can brush the sand inside the clam meat with a brush, but this method will affect the freshness of the clam, so if conditions permit, we'd better buy live clams.
