Probably the legs off a wild turkey. I grilled them along with the breast. The breast was tough, but had good flavor but I was unable to consume the legs. With all the tendons and chewiness I couldn't get it down.
I guess I don't really remember the taste one way or the other, just the fact that it was the toughest thing I've ever attempted to consume.
I crockpot those and pick the bones out before eating. I like them for anything you'd use pulled meat for.
