1. In a small bowl, mix brown sugar, mustard, and pepper.
2. When turkey has about 45 more minutes to cook (breast temperature at bone will be about 135° for birds up to 18 lb., about 145° for birds over 18 lb.), spread with half the glaze.
3. Cook 20 minutes. Brush with remaining glaze. Continue to cook until the meat thermometer registers 160°. If glaze gets too dark, drape dark areas with foil.
