Preheat oven to 200 degrees. Rub garlic into both sides of brisket. Combine remaining ingredients and mix well. Rub into brisket. Set brisket fat side up on a large piece of foil and wrap tightly. Transfer to shallow roasting pan. Bake until tender, about 8 hours. Serve hot or cold with a barbecue sauce.
NOTE: Many ovens cannot be lowered to 200 degrees. If so, cook at about 250 degrees, but reduce cooking time to 4 to 5 hours.
