Here is one of my favorites for deer roasts - thought I would share with my fellow Tradgangers. Hope you will enjoy.
4 lb roast
1/4 cup wine or cider vinegar
1/4 cup salad oil
1/4 cup catsup
2 tablespoons soy sauce
2 tablespoons worcestershire sauce
1/2 teqaspoon rosemary
1/2 teaspoon garlic powder
1//2 teaspoon dry mustard
Brown meat on all sides on cooking grill over coals.
After you remove the browned meat - bank the coals for indirect cooking.
Center meat on double thick square of heavey aluminum foil - large enough to wrap around meat and seal.
Mix all ingredients and pour over the roast in the foil.
Seal foil edges tightly.
Center roast on cooking grill.
Cover the Weber and cook 1 to 1 1/2 hours, or until meat is fork tender.
