Place brisket in 13x9 (3-quart) glass baking dish or large resealable plastic bag. In medium bowl, combine all remaining ingredients; mix well. Pour over brisket, turning to coat; cover dish or seal bag. Refrigerate 8 hours or overnight. Heat oven 325F. Drain brisket, reserving marinade. Place brisket and half of marinade (about 1-3/4 cups) in 13x9 baking dish; cover. Discard remaining marinade. Bake at 325 for 4 hours or until tender. 8 servings.
Typically we marinate it overnight and cook for 4 hours (no longer). It is delicious!
