Rotten fish
I have a good Swedish friend and his family would sometimes bring Scandinavian delicacies to him.
Surstromming and Lutfisk were the strangest and most disgusting things I have ever encountered. I did not eat them (I know that this is a little off topic but ....)the smell of either was the worst thing I have ever encountered, and eating was not really on the cards. Surstromming is essentially rotten fish and Lutfisk is prepared with causic lye.

Also please never eat Hakarl, basking shark meat, traditionally wrapped up and buried underground for a few months. An Icelandic dish. The sharks don't process urea (the poisons in piss) the same way as us and some filters out through the skin and the meat smells like piss and tastes of ammonia.

Not funny but informative perhaps....

I really want to try surstromming, and hakarl.
I keep missing the season for lutefisk, but am determined to eat some.
Only tried gravlaks so far in my quest for scandinavian fish strangeness.

one day..
I'm going to man up and try some of the Swedish fermented fish, however, my only known source has fled to the Netherlands, because she "feels weirdly at home". My mate warned me that other Swedish types were "a bit odd". She cited the fermented fish thing as evidence. I have to be honest, any foodstuff that you have to open in a bucket of water in the garden is strange...
