When I make packages of ground venison that are to be used for either meatballs or meatloaf I add both beef and pork fat to the meat while grinding, instead of just beef fat which I use for burger. Meatloaf calls for Beef,Pork and Veal, So I acquired a fawn with spots in Dec.(wouldn't shoot one myself). I used the ground from that in place of veal. Man was it good.
