Now the best are conch and Hawaiian scallop.
Conch is divided into several types. One kind of shell is reddish, and the common people call it spicy snail. This kind of conch is not expensive, just 7~8 yuan a catty, but it tastes bad. The shell of conch is gray, and the price varies according to individual size.
Hawaiian scallops can be divided into wild and cultured scallops in the market. The wild scallops are only 10 yuan/kg, while the wild scallops are about 30 yuan. Since most people can't tell whether they are wild or cultured, I personally suggest buying cultured scallops, which have the same taste.
If you want to buy it, it's still cheaper at the big food market. The Darkmouth son upstairs said that it will be closed after 7: 00 in the morning.
For reference.
