If you eat brains, does that make you smarter?
I tried some canned brains several years back, just a forkfull; don't even remember what they tasted like, though I remember I didn't dislike them....
There's a store near Concord, NH (for you locals dying to try this stuff) called The Healthy Buffalo. They sell various alterna-meats, like the named Buffalo/Bison, but also all kinds of others. Deer/Elk, Wild Boar, Alligator, Ostrich, and my new favorite, Kangaroo; probably a few more I don't recall.
I've tried eel and fish eyes (in Hong Kong for eel and Japan for fish with eyes). One of my favorites was a little narrow place in Hong Kong that specialized in Congee, a kind of rice porridge. I tried some of my co-workers Congee with Pig's Blood and Thousand Year Egg. Quite tasty, actually.
I probably ate bugs as a kid, but that doesn't count on the gourmet scale I suppose.
