1 the first move put oil. Many friends will put some salt on the clams after they buy them home, as long as the salt is moderate, the clams themselves will spit out the sand in their stomachs, but this process takes longer. In fact, pouring oil can have the same effect, and the time to do so is much less than pouring salt.
2The second trick is to pour warm water. This is the cleanest and quickest trick. After the clams bought home, pour about 40 degrees of warm water, in such a water temperature clams will continue to spit out of their stomach sand, does not take a long time clams in the body of the sand will be spit out a clean. But be sure to control the water temperature at about 40 degrees, too hot will be scalded to death clams, too cool to play a role.
3The third trick is an immediate one. Whether your clams are spitting sand or not, as soon as you're ready to start cooking them, be sure to prepare a pot of warm water and blanch the clams in the warm water. You will notice that in the warm water the clams spit out a lot of white foam as well as sand, and the foam is full of dirt. Here to remind you a point, put in warm water blanching time must not be too long, time the clam will be cooked, you then go to the processing production, the meat of the clam will become old, it will not be delicious.
I hope my answer to another you satisfied!
