I've ate about ten pounds off mine so far, and honestly it isn't that bad. No question it's tough, I tried grilling backstraps and that was edible, but man it was a jaw workout. It's got a very mild flavor, and the burger has been great.
I've got a big chunk of roast I'm going to try corning here soon, about five pounds of stew meat to mess around with, and a whole backstrap in the freezer. Not sure what the backstraps going to be. Was thinking of smoking it, but it's way too tough for that.
I sent a chunk of backstrap and some burger to California yesterday, so hopefully that chef will share what he finds works on it.
It's not whitetail or antelope by a long shot, but I definitely prefer it to some bull elk I've ate.
