Feeling hungry? Want to eat something that your ancestors enjoyed? How about Surströmming?
According to Wikipedia, Surströmming has been part of northern Swedish cuisine since at least the 16th century. However, it wasn’t confined to only Sweden. Also known as the Baltic herring, Surströmming was eaten by many people in the Baltic countries. Fermented fish is an old staple in European cuisines. The oldest archeological findings of fish fermentation are 9,200 years old and from the south of today’s Sweden.
In short, Surströmming is preserved herring. The Baltic herring is a bit smaller than the normal Atlantic herring found in the North Sea. Traditionally, the definition of strömming is “herring fished in the brackish waters of the Baltic north of the Kalmar Strait.” The herring used for surströmming are caught just prior to spawning.
