I wouldn't say it looks gross just rather unappealing.

Come on now, lutefisk is delicious when prepared properly: definitely an acquired taste though...
Mzingu,
I'm not native Scandinavian so it might be too late for me.
A collegue once told me, when he was a child he couldn't eat lut(e)fisk when he had braces (tandställning). He said the lutfisk tasted as if he was licking a battery. I think, that put me off lutefisk for good.
For uninitiated TTers - lutfisk undergoes fermentation in an electrolite-like liquid.
Wiki says "It is gelatinous in texture, and has an extremely strong, pungent odor.". Could b my own words.

@fieldgate
But surely no responsible person would serve lutefisk to an innocent child?
A friend of mine, vulgarly but rather aptly, once compared lutefisk to cunnilingus: it's not something you should try too early in life, and you have to master it to enjoy it (and to master it you have to respect its infinite complexity) - but eventually the doors of perception open and it becomes a highly enjoyable... dish.

Sounds somewhat reminescent to the fermented fish dish/condiment called "budu" consumed in the South Thailand and north eastern states of Malaysia which stinks to high heaven.
Isn't lutefisk made with lime - the building material kind that is? I saw a show that briefly went into making it and it just didn't sound appealing.

It's made with lye, I think. Although lime and lye can be used for similar purposes, e.g. turning corn into hominy, so maybe it can be made with lime as well.
mzungu, I suppose there are guys who didn't like giving head the first time they tried it, and I further suppose you and your friend may be two of them, but don't speak for whole gender.

@VinnyD
I didn't say that it's not possible to enjoy it the first time you try it, I was just pointing out that to excel as a cunnilinguist one needs a certain maturity, and that it's therefore unwise and irresponsible to serve lutefisk to minors.
