With a man in the family that hunts deer for 2 weeks each year I had to start trying to find ways to cook it all up. This is one of the better recipes I have found and use it often. Came from a Google search and then I tweaked it a little.
Mix together garlic, vinegar, soy sauce, brown sugar, Worcestershire sauce, sesame oil and water.
Pour over venison steaks and marinade at least 4-6 hours or overnight. Venison is not very fatty so the longer you marinade the better.
Preheat barbecue to 500°F making sure to season the grill well with oil of your choice. Remove steaks from marinade and reserve sauce for gravy.
Sear each side of the steak, approximately 3 min each side. Turn down grill to low and allow to cook for another 10-15min depending on your preference. I prefer mine medium rare.
Meanwhile take the reserved marinade and pour into small sauce pan. Bring to a boil. Add enough beef gravy granules( I use Bistro) to thicken sauce. Add a bit at a time so as not to over thicken. (If you do just add a bit of water to thin).
Remove steaks from grill, serve with prepared gravy.
