Coca Cola® Marinade and Gravy


1 cup Coca-Cola
1 cup cooking oil
1 tablespoon A-1 sauce
1 clove garlic, crushed
2 tablespoons Worcestershire sauce
2 tablespoons onion powder
2 teaspoons soy sauce
1 can mushrooms
flour






Combine all of the ingredients and mix well.. Marinate meat at room temperature for at least 2 hours or overnight in refrigerator. Cook roast as usual, using marinade to baste a roast often. Use a meat thermometer for desired doneness.
When done, use drippings and remaining marinade for gravy, thickening with flour if desired.
