What's the difference between a bay scallop and a sea scallop?
A bay scallop is a small scallop found mostly on the East Coast. Bay scallops come about 100 to the pound, and their meat is much sweeter than the less expensive sea scallop, which is about three times larger and has a chewier texture. Bay scallops are in season in the autumn, whereas sea scallops are available from fall to spring.
Small calico scallops, sometimes marketed as bays, are not the same thing.
