I think it is boiled or steamed crab but ready prepared for you to eat.
They also include the dark meat either side of the shell with the white in the middle.
It really looks good.
Do you have crab cakes there? They pick out all the meat and blend it with some things and some spices and it is a circle about three inches in diameter and about a half inch thick which is then fried.
We also have deviled crab, which is crab meat with breading on it. Very good eaten with a dash of hot sauce on them.
