I am Swedish and I never tried surströmming. Most swedes had not tasted it I guess.
I was invited to a so called surströmmingsskiva but I left the party early because of the smell...
I've heard from tourists many think that this is something we eat on a daily basis. Which is not true. Its exotic even for me.
Surströmming is most popular in the north of Sweden, on the east coast.
Btw ...
The icelandic rotten shark Hakarl is even worse.
