I've had it, and it wasn't too bad, although *very* rich.. The stuff I had was essentially moosemeat jerky, dried and chopped up fine (I believe actually cuisinart'ed mixed about half and half with melted lard and a healthy dose of dried saskatoon berries and rosehips for good measure, then made into fist size balls. I'm sure traditionally the fat would have been rendered buffalo or bear - pretty sure the stuff I had was just plain old lard

A good ball of it would keep you going for a while, even in the cold, and while it's definately a hunger buster, I wouldn't call the stuff I had anything like amazing.
