Snails, and also the norwegian dishes lutefisk and smalahovud. The smell of lutefisk alone makes me nauseous.

I've eaten some sort of whale meat sometime when I was a kid. It wasn't all that special. I forgot what kind it was.

As for what i think is "fine" to eat from a moral or ethical standpoint, whatever isn't an endangered species, isn't killed just to eat a very small portion for so to throw away the rest, and isn't killed in an unnecessarily slow or painful way.

I also can't stand broccoli. I can eat it if it's mixed into something else and the broccoli taste is overpowered by other tastes, but otherwise, that's being left on my plate no matter where I eat.
