Gravlax and/or Gravad lax (Swedish), also known as Graved laks (Danish), Gravlaks (Norwegian), Graavilohi (Finnish), and Graflax (Icelandic) is a Scandinavian appetizer consisting of thin sashimi-like slices of salmon cured in salt, sugar and dill.

Gravlax is traditionally served with gravlaxsås, a dill and mustard sauce, and crisp bread.

During the Middle Ages, gravlax was made by fishermen by salting the salmon and lightly fermenting it by burying it in the sand above the high-tide line. The word gravlax comes from the Scandinavian words grav, which means literally "grave" or "hole

in the ground" (in Swedish, Norwegian and Danish), and lax (or laks), which means "salmon", thus gravlax is "buried salmon", or, more literally, "entombed salmon".oday fermentation is no longer used in the production process. Instead the salmon is cured in salt, sugar and dill.
