Haihong is shellfish seafood, which is divided into wild and cultured. It is normal to have whiskers and white spots on the shell. The so-called tentacles are algae attached to the sea rainbow shell. The so-called white spot is another kind of shellfish barnacle attached to the sea rainbow shell, so don't worry about it. When cleaning the rainbow, brush off the sludge on the shell with a brush, and it doesn't matter if other attachments can't be brushed off. After cleaning, the meat will be steamed out of the pot quickly after the fire is steamed to the opening. If steamed for too long, the meat will shrink and harden. Raw sea rainbow can't be put into water when it is bought home, so its juice will be diluted by water, which will affect its freshness.
