Oysters are divided into shelled and unshelled, oysters with shells have relatively weak heat transfer capacity and need to be boiled for about 10-15 minutes; unshelled ones are able to come into direct contact with the water surface, and can be boiled for 4-6 minutes to cook and kill parasites.

How long it takes to cook oysters should also be judged with the size and number of oysters, under normal circumstances, the larger the head of the oyster, the more the number of oysters, the longer the cooking time; if the oyster head is small or the number of oysters is not much, the cooking time will be relatively short.

When cooking oysters, first wash the oysters, boil the water over high heat, add a spoonful of refined salt (salt can be sterilized), and then put the oysters; high-fire burn 3-5 minutes, because the oysters are relatively easy to cook the old, you need to observe at any time, cook to the oyster shells open on the oysters can be fished out of the drained water to eat.
