Fisk sauce is a traditional Scandinavian condiment made primarily from fermented fish, often herring. It is typically seasoned with spices and sometimes includes ingredients like vinegar or sugar to enhance its flavor. The sauce is known for its strong, salty taste and is commonly used in various dishes, particularly in Norwegian and Swedish cuisine. This sauce is often served with potatoes, bread, or as a topping for smorgasbord platters. While it may not be familiar to everyone, fisk sauce is a staple in many Nordic households and is appreciated for its unique flavor profile and cultural significance.
