Ingredients:

4 (8-ounce) sirloin steaks, cut about 1 to 1 1/2-inches thick
2 teaspoons mustard powder
1/4 teaspoon ground allspice
1/2 teaspoon freshly ground black pepper
1/2 teaspoon salt
5 tablespoons packed brown sugar
2 tablespoons ketchup
2 tablespoons Worcestershire sauce
1 tablespoon prepared mustard
1/2 teaspoon Tabasco sauce
2 tablespoons white wine vinegar
1 teaspoon paprika

Method:

1. Mix the mustard powder, ground allspice, black pepper, salt, and 1 tablespoon of brown sugar together in a small bowl.
2. In another bowl, mix the remaining sugar with the rest of the ingredients into a smooth paste for the deviled glaze.
3. Rub the dry spiced sugar mixture on both sides of the steaks and set them aside for at least 45 minutes, or until you are ready to cook.
4. Brush the steaks with some of the deviled glaze and barbecue over medium-hot coals for about eight minutes for medium-rare steak, turning and basting them with more of the deviled mixture now and then.
