Rauðkálssúpa
Rauðkálssúpa is a traditional Icelandic soup made primarily from red cabbage. Its preparation typically involves simmering shredded red cabbage with water or broth, often incorporating ingredients such as potatoes, onions, and sometimes a touch of vinegar or lemon juice to enhance the cabbage's vibrant color and flavor. It can be seasoned with salt, pepper, and other herbs according to regional or family preferences.
The soup is known for its striking deep purple hue, a direct result of the red cabbage.
