During the Middle Ages, gravlax was made by fishermen, who salted the salmon and lightly fermented it by burying it in the sand above the high-tide line. The word gravlax comes from the Scandinavian word grav, which means literally "grave" or "hole in the ground" (in Swedish, Norwegian, Danish and Estonian), and lax (or laks), which means "salmon", thus gravlax is "salmon dug into the ground".
