Bien Mai is a triangle scallop plugning deeply to the sea bed. It size is about 20cm long and 8cm at the widest. The meat is useless but the sinew is extremely tasty. Someone said that the meat of Bien Mai is hamful but a lot of people confirm that the meat is not used because it is not as delicious as the sinew and Phuquoc residents who are experts in choosing seafood don't want to take it. The sinew is only about 1 penny size round, 6mm thick. In comparison to the great size of through-away meat, the islanders here are truly watse of seafood resources. The Bien Mai sinew is cooked for various dishes: grilled sinew with fish sauce and pepper, grilled sinew with salted soya cream, grilled sinew with salt and chili, braised sinew with pine-apple, sinew porridge...Sinew has good flavor, sweet and not as soft as scallop meat. If you have a change to try, you will never forget it special flavor. For this reason, the islanders introduce it to the visitors.
