We started this a few years ago, first in a crockpot eventually moving to oven roasting. Little changes between the two, but by George it's the best damn turkey you've ever tasted.
Thaw turkey 24 hours in advance. Make sure that bird is nice and thawed.
Preheat oven to 325.
Place turkey in a roasting pan. Dump 3-4 (or more) bottles of Angry Orchard Hard Cider Cinfully Apple on, in, and around the turkey. If using a Crock Pot, submerge the bird. Put a stick of butter inside the turkey, and one on top (just set that brick up there). Add Tiny Town Turkey Rub to the cider bath and all over the turkey, coating it. Mix some of the turkey rub in with the cider and use a baster to splash the combination up inside the turkey.
Add a sprinkle of salt and pepper (no more than a teaspoon on average).
Cook until 165-170 degrees as checked with a meat thermometer. Check often and splash with the cider/butter/seasoning mixture every hour or so when checking temperature.
