National Clams on the Half Shell Day

National Clams on the Half Shell Day celebrates clams served in their simplest presentation: with the top shell removed and the meat resting in the lower shell. Observed annually on March 31, the food holiday gives seafood lovers an excuse to enjoy clams raw, steamed, grilled, smoked, or baked.

Clams are bivalve mollusks with two hinged shells. When served on the half shell, they are often presented on crushed ice with lemon, mignonette, or cocktail sauce. Although the phrase usually refers to raw clams, cooked preparations can also be served this way.

The holiday’s creator and exact origins are unknown. The earliest located print reference to a March 31 “National Clams on the Half Shell Day” dates to 2001 in Texas. Its connection with a variety of preparations makes it easy to celebrate whether you prefer a chilled raw clam or a cooked dish.
