Whoa!!! surstromming, you're a brave man. It doesn't taste too bad, but that stuff stinks to high hell!!!! I would put that in the top 10 of things I would not eat again. I eat all the local "weird" things when traveling, and there are only two things that made come close to puking. Hakarl, which is fermented shark in Iceland and stinky tofu in Hong Kong. Damn that shit was beyond puke factor 5!!!
Smogasbord though, everyone loves a smorgasbord!
Enjoy XMas!
