This is a recipe I inherited from my aunts. I come from a family that really is into hunting and this marinade has been passed down for generations. If you prefer not to eat venison it works great on beef as well.
Place unfrozen beef or venison roast or tenderloin in 1 gallon ziploc bag. Set aside.
Mix together remaining ingredients and poor over meat. Allow to marinade between 1 to 12 hours in the fridge.
Cook in your favorite manner. I cook it on low in my crockpot for 12 hours then high for 3 hours. Or you can roast it in the oven at 350 degrees for 45 - 60 minutes or until cooked to your liking. You can cut the tenderloin into 1/2" thick piece and grill to the pinkness you like. It is versitale and tastes great any way you cook it.
