After buying the fresh sea rainbow home, use scissors to cut the parts that are connected together, so that it is more convenient to clean the later steps as well as cooking steps.

2, soak

Soak the processed rainbow in water for 10 minutes to clean the surface impurities, and then soak the rainbow in lightly salted water for 30 to 50 minutes, so that the rainbow can spit out the sediment.

3, brushing

If there are still some visible stains on the surface of the sea rainbow, you can use a toothbrush or other small brush dipped in salt, and then gently brush on the shell of the sea rainbow.

4, processing

After the rainbow is cleaned, soak it in water again, at this time open the rainbow and remove the black internal organs, so that the processed rainbow can be used directly for cooking.
