SERVES 4 So many kinds of crab to eat in this country and so little time! Joes Stone Crab Restaurant, in Miami Beach, is a mecca for serious seafood lovers. I have eaten there a couple of times and each time I was terribly happy. The surroundings are nice, the staff terrific, and the stone crab claws are superb. They sell more of this rare delicacy than just about anybody, and they have been doing so since 1913. The thing that makes the meal is their special mustard sauce. Jo Ann Sawitz, the charming owner, was kind enough to give us the recipe. Beat the dry mustard and mayonnaise together for 1 minute. Add the remaining ingredients and beat until the mixture reaches a creamy consistency. Chill. The legs are dipped into this sauce with the fingers and enjoyed. Even your fingers will taste good with this sauce. From . Downloaded from Glens MM Recipe Archive, G Internet.
