How to choose sea rainbow
Sea rainbow, like all seafood is the fresher the better, if the sea rainbow is dead not only the flavor and texture is not good, but also easy to eat uncomfortable. It is important to know that sea rainbow with cracked mouth are dead from lack of water, you should buy sea rainbow with closed mouth, so that the sea rainbow is fresh.
When you buy a sea rainbow, you have to choose those with a big head, because a big head of sea rainbow meat is more, a small head of sea rainbow meat is as small as shrimp skin, eat up the effort not to say that it is not cost-effective. I don't know if you've heard of this saying, but you should buy sea rainbows with mud on them for their freshness, and those without mud are those that have been sitting around for a long time. In fact, the crew of the sea rainbow in the salvage of the time directly to wash it, transported to the shore of the sea rainbow are clean, so we can not fall into this.
