When I was a kid we'd walk down to the shore during low tide and throw big rocks on the beach below the tide line. When water squirted up out of the sand, we'd dig there to find a type of small clam that sprays water. Then we'd literally steam and eat them. You are supposed to soak them in water to let them filter out the sand for a day, but generally we just dealt with a little grit for the immediate satisfaction.
