blanching is a cooking method, which is usually used to remove impurities and odors from ingredients and make them more tender and smooth. Oyster is a common seafood ingredient, and the process of blanching oyster can help remove dirt and impurities on the surface of oyster meat. The method of blanching the oyster is as follows:

1. Wash the oyster first, and clean the impurities such as sediment and seaweed on the surface of the shell.

2. Boil a pot of water with enough water to completely cover the oyster.

3. after the water is boiled, put the oyster into the boiling water and continue to boil for 1-2 minutes.

4. The cooking time should not be too long, so as not to overcook the oyster meat and harden the taste.

5. The dehydrated oyster can be washed with cold water to stop the cooking process.

6. finally, if you need to add flavor, you can add some salt to the boiling water before the oyster is blanched, so that the oyster can absorb some salt flavor during the blanching process.

It should be noted that the time and method of blanching oysters may also be different due to personal tastes and specific recipes, which can be appropriately adjusted according to your own preferences and needs. At the same time, it is very important to ensure that oysters are fresh and washed to ensure the quality and safety of ingredients.
