I don't make a lot of burger outta mine, mostly cut it into steaks and roast and stew sized chunks, for the steaks I sprinkle it with mint and thyme and drizzle some virgin olive oil on it and put it in the fridge over night, then throw it on the grill over mesquet coals till its medium rare, for the roast, I either inject it with teryaki or soy sauce and let it marinate overnight, or I'll give it a liberal coat of olive oil and mint and thyme and inject it with puriee'd garlic and put it in the smoker with mesquet wood for 50min a pound, if I cook it in the oven, I put a heavy coat of course black pepper and bake it at 325deg till internal temp reaches 145deg then let it set for 20min before carving.
all my recipes are for medium rare, if deers cooked to well done, it gets tough and chewy, theres also some pretty good recipes for lamb that work well with the deer meat.
