Remove the neck and innards from turkey, making sure both cavities are empty. Rinse turkey, inside and out, thoroughly. Stuff both cavities with dressing. Melt 1 Cup Butter and pour over turkey, making sure that the skin has been completely covered with butter. This will insure a more moist turkey. Cover with foil or roasting pan lid. Cook, according to time table at 325 degrees. After 1/3 of the cooking time has passed, uncover turkey. Baste turkey a couple times while covered, and then every 15-20 minutes thereafter. Remove turkey from oven when done and let sit 20 minutes before carving.
