I've done several.......wet brine is a must, Alton Browns is well known but the Pioneer Woman has a good one online.Have never had the cajones to try smoking a turkey. We host T-giving every year, would like to try it sometime but will have to try a test run at some point prior to the holiday. How long you think it would take for a 20-22lb bird at 225?
Smoking some back ribs tomorrow.
Butter under the skin, some simple rub on the outside.
I start around 180 and kick it up every hour.....250, 300, and 350 for the last hour to crisp up and brown the skin. Takes about 4 hours total to hit 165 internal temp. That's for a whole bird, no stuffing.....you could also spatchcock or do turkey breasts only.
