Shellfish is the star in the traditional Italian pasta dish linguine ai frutti di mare. Our recipe calls for five varieties: clams, mussels, scallops, shrimp, and squid.
The easiest way to remove sand from clams and cockles is to purge them in a saltwater solution: Mix 2 tablespoons fine sea salt (not iodized or kosher) with 4 cups water in a bowl. Add shellfish and let stand for 30 minutes. Then scoop out shellfish and rinse, discarding any opened ones.
