Hmm, ham radio potluck picnic list has items they want people to sign up to bring . What the heck is "Surströmming" and what joker inserted that in the spreadsheet? #potluck
LOL... I am curious if you can even buy that here. https://en.wikipedia.org/wiki/Surstr%C3%B6mming
Surströmming - Wikipedia

I'm guessing not, from Wikipedia:

"German food critic and author Wolfgang Fassbender wrote that "the biggest challenge when eating surströmming is to vomit only after the first bite, as opposed to before"

@ai6yr Can't be any worse than that Icelandic delicacy Hákarl (fermented shark) - best taken with a chaser of aquavit. Yikes! I agree with the Wikipedia article: "Those new to it may gag involuntarily at the first attempt to eat it because of the high ammonia content."
