Back strap and the tenderloins. I like to cut the back strap into inch thick sections, butterfly them, pound them with the tenderizing hammer, batter them and fry it in my deep frier. The rest of the deer goes into, hamburger, sausage and/or snack sticks. I take a chuck roast and trim the fat off it then cube it up. Then I mix 1/3 of it with 2/3 deer meat and grind it into hamburger, deer meat is a little too lean by itself for good hamburger. One time I mixed 1/3 wild hog, 1/3 beef chuck and 1/3 deer and ground them together, it made great hamburger. For the sausage I mix in a third of lean pork and sausage seasoning. I have the professional processor make the beef sticks.
