sateiseen

Sateiseen is a traditional Finnish dish that originates from the coastal regions of southwestern Finland, particularly the Åland Islands. The name "sateiseen" is derived from the Swedish word "sill" (herring), indicating that the dish is primarily made with herring as its main ingredient. It is a type of open-faced sandwich, often served as a cold dish during summer months.

The dish typically consists of a slice of dark rye bread, known as *tumma ruisleipä*, topped with a layer of herring fillet. The herring is usually marinated in a mixture of vinegar, sugar, and various spices, such as dill, allspice, and sometimes mustard or horseradish. The marinated herring is then lightly fried or baked until crispy on the outside. Additional toppings may include sliced onions, pickled cucumbers, or a dollop of sour cream or mayonnaise.

Sateiseen is often enjoyed as a light meal or snack, particularly during outdoor gatherings, picnics, or summer festivals. It reflects the Finnish tradition of utilizing local ingredients and simple preparation methods. The dish is also a popular choice in Finnish cafés and restaurants, where it may be served alongside other classic Finnish foods like *karjalanpiirakka* (Karelian pies) or *salmiakki* (salty licorice).

While traditionally made with herring, some variations may use other types of fish or even vegetarian alternatives. The dish remains a beloved part of Finnish culinary culture, appreciated for its simplicity and the balance of flavors it provides.
