Here's one for ya....I am of Swedish decent and every holiday our family has something called Ludefisk. Basically it is cod that has been soaked in a mild lye water and then boiled. Makes sushi seem tame by comparison!! LOL! It is basically the consistancy of slime and then topped with a white gravy. The kids in the family seem to go thru an acclimation to it...each year they are served just a little more than the year before. After about 20 years or so, I became quite fond of it. Think it is a nostalgia thing for me since we only had it on special occasions. Oh yeah, and then there's Ostakaka...a curdled milk pudding served with lingonberrys....
