Surströmming – fermented herring
Food wise, well… where I come from we have this delicatessen
Surströmming, Swedish “soured (Baltic) herring”) is a northern Swedish dish consisting of fermented Baltic herring. Surströmming is sold in cans, which often bulge during shipping and storage, due to the continued fermentation. When opened, the contents release a strong and sometimes overwhelming odor, which explains why the dish is often eaten outdoors. A Japanese study has shown that the smell of a newly opened can of surströmming is the most putrid smell of food in the world, beating similar fermented fish dishes such as the Korean Hongeohoe or Japanese Kusaya. But I love it, but you do need a lot of schnaps though for this dish, but that goes for a lot of Swedish food.
I took this to my Norwegian uncle and we actually managed to get the fire department called out to his place because they actually thought it was a gas leak somewhere after complaints from the neighbours.
