Is that meat from an older animal? I read that American lamb has just been bred a lot bigger than Australian for NZ lamb but maybe I'm wrong. I know the American vs. imported lamb I've seen puts the American lamb being way biger in size.
And I agree, I'd give my left pinky toe to be able to get old sheep or mutton here in Alabama. That gaminess is what I love about that meat.
