I am following a recent NY Times turkey roasting recipe. I have to smoke it (an 18 lb super expensive heritage model) at 450 for 30 minutes and then 350 until done. My plan is to fill up the ring of my 22" and dump two chimneys of gray coals on it. When the all of the coals are gray (or top layer?), I will throw on the apple wood chunks. When they start to flame I plan to put the turkey on. The forecast, unfortunately, is for temperatures in the upper forties. Will I make it? Any tips? A few years ago we had a colder Thanksgiving. I had failed to fill up the ring. I used a leaf blower to get the temperature up to 300. It worked but coated the turkey in fine ash. i will put the bird in the oven to finish it if necessary but I going to start and go for at least two hours on the smoker no matter what.
