Marmite. Blackish/brown foul-smelling spread. Tastes wonderful if used sparingly on toasted full-grain bread and butter. SPARINGLY! I've seen confused countrymen spread it like peanut butter and then complain about how it tasted.
Wolf. Tasted like... well, I can't really describe it. It was good with some marinade. The off-putting thing was that the head was sitting just across the room from where we were eating, it seemed as if it was watching us.
Steak Tartar. Raw minced steak mixed with egg. It's a delicacy and looks and smells great, is eaten on toast. In moderation, it's excellent, but where I ate it they served large portions and I was not disposed to insulting the people I was eating with by not finishing. I was served just over a pound of it. Halfway through I felt ill. Afterwards, I had to puke. Safe to say now I stay the hell away from it!
Foie Gras. Goose liver pate. Many people are put off by the smell of it, and depending on how it's cooked it can look absolutely disgusting, like a loaf of alien flesh. However, when on some warm brioche or in a salad with truffles, it's superb.
