Place brisket on heavy duty foil large enough to enclose meat. Put in a shallow baking dish. Mix remaining ingredients, brush over entire surface of the brisket, and seal in the foil. Refrigerate for 24 hours. Bake in foil at 275 degrees for 5 - 5-1/2 hours. Allow to rest for 20 minutes before slicing across the grain.
