Crab meat is used for cocktails in the same way as Oysters, clams, and LOBSTER. In fact, no better appetizer to serve at the beginning of a meal can be found. To make crab-flake cocktail, remove the meat from the shells of cooked hard-shelled crabs in the way just explained, and chill it. Then place it in stemmed glasses and serve with cocktail Sauce.
