Gravlax is a traditional Scandinavian dish made from raw salmon that is cured with a mixture of salt, sugar, and dill. The curing process typically takes a few days, allowing the flavors to penetrate the fish while preserving its texture. It is often served thinly sliced, accompanied by mustard sauce, bread, or crispbread. This dish has its origins in the Nordic countries, where fishermen would cure salmon to preserve it before refrigeration was available. Gravlax is popular in many parts of the world today, appreciated for its delicate flavor and versatility in various culinary applications.
