What size turkey? Plan on about 1 lb per person.
How to thaw? If frozen, thaw turkey in its packaging on a tray in the fridge; it will take 24 hours for every 4 lbs. Figure 3 to 4 days for a 15 lb bird.
What to do after it's thawed: Unwrap and remove giblets and neck; carefully rinse inside with cool water to melt any remaining ice crystals. Pat dry inside and out. Tuck wings under, if desired. Season as recipe recommends.
