Most recipes I've found call for equal parts ground beef, pork, and potatoes, with the addition of ground onions and salt and pepper to round it out. My adaptation swaps out the beef for elk (or any other venison), reduces the amount of pork to about half that of the venison along with an equal measure of potatoes. I've since made it with and without onions and prefer the latter, though both are delicious. A few recipes call for allspice, though I really like how this recipe lets the flavor of the meat be the star.
