In a small bowl, combine the salt, pepper, savory and sage. Rub 1 tablespoon of seasoning mixture in turkey cavity. Place the pears, onion and celery in turkey cavity; tie drumsticks together. Place, breast side up on a rack in a roasting pan. Combine butter and remaining seasoning mixture; brush over turkey. Bake, uncovered, at 325° for 3-1/4 to 3-1/2 hours.
Meanwhile, combine orange marmalade, orange juice and honey in a saucepan. Bring to a boil. Reduce heat; simmer, uncovered, for 15 minutes or until thickened, stirring occasionally. Set aside and keep warm. When turkey begins to brown, cover lightly with a tent of foil. Bake 1 hour longer or until thermometer reads 180°, brushing occasionally with the orange glaze. Cover and let stand for 15 minutes before carving. Thicken pan juices for gravy if desired.
