The surf clam (also known as the sea, hen, or bar clam) grows up to eight inches wide and is tough. Commercial plants like Eastern Clam, in New Bedford, Massachusetts, separate the surf clam's flavorful foot and tenderize it for steaks or strips. The rest of the clam is chopped for chowder, fritters, or sauces. We like the Sam's Clams brand, which is widely available. For clam sauce in a pinch, however, a can of whole clams and some bottled clam juice simmered with butter, a bit of garlic, and a handful of parsley works beautifully.
