Updated August 1, 20261 min readCited sources

Surströmming is a Swedish fermented fish dish known for its strong smell and seasonal tradition. It has been part of northern Swedish cuisine since at least the 16th century.

What it is

Surströmming is made from Baltic herring that is lightly salted and fermented. The name means "sour herring" in Swedish. The fish continues to ferment after being canned, which can cause tins to bulge.

Why it matters

What began as a practical preservation method during times of salt scarcity became a regional delicacy, especially in northern Sweden and the Höga Kusten region. It is often eaten outdoors in late summer or early autumn as part of a social gathering.

Key details

Surströmming is typically served with flatbread, potatoes, onions, tomatoes, and dill. Its pungent aroma has made it a cultural curiosity worldwide. In Canada, it appears in specialty import shops and Nordic communities as a heritage food.

In short

  • Fermented Baltic herring, lightly salted
