Surströmming is a Swedish food made from lightly salted, fermented Baltic herring. It has been part of Swedish cuisine since at least the 16th century and is especially associated with northern Sweden. The dish is known for its strong smell and is commonly eaten as a seasonal delicacy.

History

Surströmming is a traditional Swedish preserved fish dish that dates to at least the 16th century. Sources associate its origin with northern Sweden and note that it arose in a period when salt was scarce.

Preparation

The dish is made from Baltic herring caught in spring, salted just enough to allow fermentation, and stored for months. The fermentation continues after canning, which contributes to its characteristic aroma and texture.

Cultural role

What was once a practical preservation method became a regional delicacy, especially in northern Sweden. It is commonly eaten in late summer or early autumn and is often the centrepiece of a surströmming meal or social gathering.

Serving and reputation

Surströmming is usually eaten with accompaniments such as flatbread, potatoes, onions, tomatoes, and dill. It is also widely known internationally for its especially strong smell, which has made it a cultural curiosity beyond Sweden.
