Brining is an excellent way to keep a turkey moist, I believe.
My mother would get up early to put the turkey in the oven, but there were 7 children in our family, so we always had a big bird. Our turkey this year is only 11 pounds. :)
I have been brining for 15 years or so! Can’t think of doing it any other way. I use Melinda Lee’s Apple cider brine. It rocks. You will need to foil the bird loosely after it browns because of the juice in the brine.
