Kalakeitto or fish soup has been a staple of traditional Finnish cuisine for a long time. Although there are numerous ways to prepare this classic Finnish specialty, it typically consists of cleaned and filleted fish chunks and diced vegetables that are simmered in a rich, buttery fish broth.
Carrots, potatoes, onions, and leeks are among the most common vegetables used for the soup’s preparation, while the choice of fish includes salmon, rainbow trout, vendace, pike, perch, zander, or burbot. Traditionally, the soup is enhanced with the addition of butter and cooking cream (ruokakermaa), and it is usually flavored with dill, allspice, bay leaves, salt, and pepper.
