Surströmming Surstromming is a type of fermented Baltic Sea herring. During production of surströmming, just enough salt is used to prevent the raw herring from rotting. A fermentation process of at least six months gives the fish a characteristic strong smell and somewhat acidic taste. According to a Japanese study, a newly opened can of surströmming has one of the most putrid food smells in the world, stronger than similarly fermented fish dishes. 300g. can approximately contains 10-12 pieces.
