yes ,fat does make any meat stay together better. we add 20% beef fat. pork will work but it doesn't freeze as long . i take 10lbs of chunked deer and the fat and spread it out in a big flat pan. then dump a whole can of weber blazin burger seasoning over it and mix. then grind it. i make mine into patties and vacuum seal 2 in a pack. cook them pink in the center. i like to serve with one strip of bacon on the bottom and a hand full of crumbled blue cheese on top.sweetness of the bacon and the bite of the blue cheese are the perfect combo.
