Just melt a little real butter and pour over meat before you make the burgers. Works great for me.
So funny story time; I add pork fat to my elk sausage. The local Mexican market is the best source for pure pork fat. The butcher there goes through a lot of pigs and they save everything.I had a guy tell me he would go to the butcher and get ground pork. I think if I were to go that rout I would just get a pork shoulder , they are alway on sale, and grind it myself, they are very fatty, then add it to the elk in which ever % I settled on.
