1, warm water. The clams bought from the supermarket should be put into the water as the first step to go home. We need to prepare warm water of about 50 degrees to soak them. If the temperature is too high, they will be burned to death. If the temperature is too low, it will not accelerate their breathing and help them spit sand. Soon, they will start to vomit.

2, salt+cooking oil. If time is short, you can add a small amount of salt and cooking oil to warm water to make Meretrix meretrix spit sand quickly. Salt can stimulate the stomach of Meretrix meretrix and promote sand spitting. Sea salt is better. Edible oil is immiscible with water, and its density is low, so it will float on the water surface, which will accelerate the breathing of Meretrix meretrix and spit sand faster.

3. shake it. If you want to eat it, you can also put the clams in the pot, stir them in one direction with chopsticks, then cover them, shake them up and down for ten minutes, and open the lid to see. There is already a lot of sediment in it, so you can fry it directly after washing it with clear water for several times.
