Gravlax or gravad lax (Swedish, Danish), gravlaks (Norwegian), graavilohi (Finnish), graflax (Icelandic) is a Scandinavian dish consisting of raw salmon cured in salt, sugar, and dill. Gravlax is usually served as an appetizer, sliced thinly and accompanied by hovmästarsås (also known as gravlaxsås), a dill and mustard sauce, either on bread of some kind, or with boiled potatoes.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 and Danish), and lax (or laks), which means "salmon", thus gravlax is "salmon dug into the ground".Today fermentation is no longer used in the production process. Instead the salmon is "buried" in a dry marinade of salt, sugar, and dill, and cured for a few days. As the salmon cures, the moisture turns the dry cure into a highly concentrated brine, which can be used in Scandinavian cooking as part of a sauce (Ruhlman 2005, pp. 51-52). This same method of curing can be used for any fatty fish, but salmon is the most common. Modern variations on the marinade can include fennel and Pernod, black pepper and coriander seed, or horseradish (Ruhlman 2005, p. 51).Commercially prepared gravlax is sometimes smoked, and as such is incorrectly termed "gravlax".
