Some of the stranger things I’ve tried…
Chocolate dipped grasshoppers (kr; sort of like a crispy/light nutty taste), live octopus (kr; sort of like jellyfish – not much taste but a touch oceany, if that makes any sense, too chewy), live lobster (jp; very light and delicate with a sweet hint), horse (fr; sort of reminded me of farm raised pig), various organs across ph, jp, cn, and near home (heart [probably my favorite], brain [cow, monkey], tongue, kidney, liver [many different ones], stomach), pig blood (ph; really rich when cooked right); jellyfish (basically bland, or maybe i’ve not had it properly made), chicken eggs (ph, the crunchy one’s, I forget their name; salty, much better than the imagery suggests), tripe (a lot like what it was cooked in, a little tough but not as bad as you’d think). Alligator (I didn’t think it tasted like chicken, but then maybe it was because I knew what I was eating), snake (chicken), Others like @wilma said I don’t really count as exotic since I grew up eating some of them (obviously that’s a key when defining what’s exotic) bear @Doctor_D it’s legal where I live (restricted), but might vary state to state (it’s own very strong, greasy/gamey, taste), squirrel (squirrel, a bit like rabbit), rabbit (farm chicken), deer (probably closest to buffalo?), duck (duck), moose (more like wild beef if you can picture that), pheasant (sort of like wild turkey), wild turkey (turkey but much richer, nuttier), dove (chicken), buffalo (richer than beef), goose (stronger turkey and greasy, greasy, greasy)... All sorts of different ice creams that you don’t normally get (corn, bacon, crab, jellyfish for ex.)
For me I just love trying new things when I travel, I always eat local and try to get as much variety as possible. I’m open to most anything and have a pretty strong stomach. The roasted spiders in VN turn me off a bit though.
