Combine all of the seasoning ingredients in a bowl and rub the mix into the beef. Place the brisket in a roasting pan. Slowly cook the beef for 1 hour, turn the beef and cook one hour more before covering with a tight fitting lid. Continue to cook with the lid tightly in place for 2 1/2 to 3 hours more. This will render most of the fat. Carefully pour off and discard the fat. Allow the beef to rest for 20 to 30 minutes before serving.
