Brine that turkey, and then cover the breast meat with tinfoil so it isn’t totally dried out by the time the thigh meat is done. Or else butcher the thigh and leg off and cook them for 1/2 or so before putting in the rest of the bird.
My mother knew how to cook a turkey, back in the day before implanted thermometers and inbred tame turkeys. Never tasted one that was like cardboard(she was from the south).
