I've always used my WSM to smoke a bird in the past and I'm still torn between tried and tested method on the WSM or going with the SF. Looks like the weather won't be a factor this year so I'll probably give the SF a shot.
Defrost 21# Turkey
Wet Brine Turkey for 48 hours in a 5 gal bucket in an ice chest filled with ice in the garage
Pat dry, put a quartered onion a few celery stalks and carrots in the cavity, S&P on the skin.
Drip Pan under the grates, Water Pans (2) on upper grates
Turkey onto the SF with smoke boost for 2 hours using Weber Hickory pellets.
Set temp at 250* and cook until breast probe hits 165*
Remove bird onto carving, tent w/ foil and allow to rest for an hour
Finish making gravy with pan drippings and finish up side dishes.
In the past when using the WSM I knew if I didn't have the bird cooking by 0700, we were looking at dinner by 1700 if we were lucky but the results were always outstanding nonetheless. This year, knowing that I can better control the grill temp, I shouldn't have to worry as much about when it'll be done. I am concerned about placement of the water pans and how effective they will be in adding humidity when they aren't directly over the heat source as in the WSM. Then again we never had any pan drippings with the WSM because of the water pan. Well life is for learning so we shall see (and learn) how it all works out. Happy Thanksgiving y'all.
