I watched it and, really, didn't think the ingredients were that strange.

I know people who've eaten goat, and know that it generally has the consistency of a very old animal. (i.e. you either tenderize the animal before butchering or you tenderize the meat after butchering or you cook it under high pressure for a very long time or - and this is the best option - you do as many of the above as possible!)
I thought they were pretty fair with the ingredients, because even though the chefs might not have worked with that particular ingredient, it didn't mean they couldn't think about the animal and figure out a parallel animal that they DID know how to work with. (And it really surprised me that neither contestant knew how to work with goat!) Also, I mean, really, with Top Chefs reputation, if I were going to be a contestant, I think I'd at least have pulled down the 1962 Joy of Cooking and read through the chapters on exotic game and on seafood prior to the start of competition.
