RE: Getting the silvery skin off the venison??
When butching friend, I cut out the hinds back straps and other meat I cut off I cut off the deer hanging and try not get too much of the silver in my grinder. I then cut the meat up into cuts I desire. To get the silver of, takes a good sharp knife. Easiest way to do a roast is to quick freeze and it cuts off much easier.
For steaks just cut up the cuts you like and freeze. When its time to cook I then worry about cuting away the outsides of the steak with the silver on.
