Preheat oven to 325°F. Remove giblets and neck from turkey. With skewers, fasten neck skin to back. Fold wings under and tie legs together. Place turkey on a rack, breast side up, in a large roasting pan. Sprinkle salt all over turkey. Insert a meat thermometer into thickest part of thigh. Cover turkey with a loose tent of foil and bake 3 to 3 1/2 hours.
Combine maple syrup and mustard in a small bowl. During last 30 minutes of roasting, spoon or brush maple mixture over turkey. Turkey is done when thigh temperature on thermometer reaches 175° to 180°F and drumstick feels soft. Breast temperature should be 165° to 170°F. Place turkey on a large platter; cover and keep warm. Let stand 30 minutes.
Meanwhile, melt butter in a 3-quart saucepan over medium heat. Stir in flour to make a thick paste. Gradually stir in chicken broth, apple cider, TABASCO® Habanero Sauce, and salt until well blended. Simmer 5 minutes or until thickened. Serve gravy with sliced turkey.
