Clams

The two main varieties of clams are hard-shell and soft-shell. Clams are sold live in the shell, fresh or frozen shucked, and canned. When buying hard-shell clams in the shell, make sure the shells are tightly closed. If a shell is slightly open, tap it lightly. if it doesn't snap shut, the clam is dead and should be discarded. To test a soft-shell clam, lightly touch its neck; if it moves, it's alive. The guideline for buying shucked clams is plumpness and clear liquid. Store live clams up to 2 days in a 40 degree F refrigerator; refrigerate shucked clams up to 4 days. Clams can be cooked in a variety of ways, including steaming and baking. All clams should be cooked gently to prevent toughening. Clams are high in protein and contain fair amounts of calcium and iron.
