Only bear I ever had was burnt, so it tasted like burnt food, which is categorically awful. Willing to give it another try...I've eaten a clam chowder that had sea cucumber in it, but I couldn't have told you which bits were clams, and which were sea cucumbers.
I don't particularly care for the taste of venison. Abalone is too rubbery for my taste, as is tripe. I've never had brains but I'm told it's very good. Organ meats in general I find distasteful. I used to like oysters a lot more until I ate a huge one, raw, on a beach on South Pender (or is it Pinder?) Island, B.C. Haven't cared for them much since.
I had alligator once, but it had squishy bits (I imagine it was the fat?) that I found disgusting. But the non-squishy bits were okay (nothing to shout about).
In general I'm willing to try just about anything (if it seems safe --i.e. disease-free).
