Until now, and because I was used to hand-grinding, I have preferred canning my venison; however, a friend loaned me her grinder attachment and, WOW!- was I impressed! In a little over an hour I had made hamburger out of 4 deer, ready to package neatly in vacuum bags for the freezer. I was impressed that the unit could handle the semi-frozen meat fed continuously without hangup or overheating, and it only required ONE grinding to obtain terrific results. Kudos, and many thanks to KitchenAid for a such a helpful product!
