1, the first method: warm salt water soak. First of all, the clams into a basin of warm water, and then in the warm water into the salt and oil, the amount based on the water in the basin. This will mimic the clam's growing environment so that it will open its shell in favor of spitting sand. The purpose of the oil is to form a film of oil on the surface of the water, which can separate the water from the air, so that the clams can breathe faster due to the lack of oxygen in the water, thus speeding up the progress of spitting sand. Then, after two to three hours of standing, we will see most of the clams open their shells, and the water is turbid, this time the clams to spit sand process is complete. If you want to shorten the time, we can use our hands to stir the water back and forth in the basin, and repeatedly change the water, so that a few minutes can let the clams spit out all the sediment.

2, the second method: boiled rinse. If you think the first method is too time-consuming, then let's learn a quick way to remove the sediment. First, pour the pot full of water and put the clams to boil with water. When the water in the pot boils, the shells of the clams are basically all open, then pour out the water and rinse the clams with water once again to clean out the sediment. However, this practice tends to affect the fresh flavor of the clams, we can let the water in which the clams were boiled cool down and filter out the sediment deposited at the bottom, and then use the clarified broth to wash the clams, which can retain part of the fresh flavor.

3, the third method: heating rinse. First of all, will buy back the clam shell sediment with water rinse clean. Then put the clams into the waterless frying pan heating for 3 minutes, when the clams one after another open, immediately pick out the opening of the clams on the faucet under the rinse, can be cleaned up its internal sediment. This practice is very simple, and the clam meat is tender, nutrients and water are not easy to lose, just bought the clams can also be cooked immediately on the table, it is really convenient.
