Fill a bowl with cold water and dissolve enough salt in it to make it taste like the ocean. Submerge the clams in the water. Let them sit for 10 minutes or until they spit out their grit. You should see sand at the bottom of the bowl. Lift out the clams and transfer to a colander. With a stiff-bristled brush, scrub them vigorously until their shells are really clean.☞ TESTER TIP: If you don’t have a kitchen brush, a clean toothbrush will work nicely in its place.
