Beef Brisket Marinade

1 small onion, chopped

2 tablespoons liquid smoke

½ cup Worcestershire sauce

2 tablespoons soy sauce

½ teaspoon ground red pepper

½ cup butter

½ cup ketchup

½ cup red wine vinegar

1 teaspoon dried mustard

Cut brisket into ½ inch strips leaving about an inch at the bottom, allowing for more of the meat to be marinated. [Don’t cut off the fat as it will easily fall off once it’s cooked.] Combine onion, liquid smoke, Worcestershire sauce, soy sauce and red pepper in a gallon-size bag. Add meat and marinate for up to two days. Once marinated, take out the meat and pour marinade into a pan. Add the remaining four ingredients and boil. Reduce sauce to approximately ½ cup and use to baste. Cook meat in a disposable casserole pan on the grill for 1 to hour on medium, basting the meat periodically and turning it over halfway through. Place brisket directly on the grill for the last 10 minutes.
