From a user who posted as an answer elsewhere:
I cooked the 22 pound turkey way to early. It's done at 10:30 and we aren't eating till 4:00. Right now I have it sitting in the roaster covered with towels and aluminum foil. What should I do? Should I keep it there for the three hours? Then it's still another 2 hours till serving.
Whatever the exact specifics, what can someone do if they end up in this situation? Similarly, what if someone wants to cook the turkey early like this - is there anything they can plan ahead for?
