I could personally identify very well with one of the questions, as it is a pet peeve of mine (and my worst hostess dinners have been due to this beast! :) OVERCOOKING your meat.
A caller wanted to know how you know when your turkey is done. Alton Brown took this question, and everyone should take note of his answer. He explained how most turkeys these days come with that little popper thing that "pops" up when your turkey is done. According to the package directions, when your popper pops, that's when it's time to take out your turkey. WRONG!
Alton explained that because of the resin that those mechanisms are kept in, it won't pop out until your turkey has reached 179 degrees. And if you know the correct temperature to cook your turkey to (Dad are you listening!?! :) - which is 165 - then you'd know that relying on that thing will give you an overcooked turkey - very overcooked at that (because don't forget your turkey will continue to cook as it rests (so important to let it rest, don't forget! 20 min or so for a large bird!)- every time.
I never knew the science behind those popper things, but because every time I've eaten a turkey that cooked using that popper, it's been drier than a baby's new diaper, I figured those things aren't worth their weight in gold :)
So, ditch that thing, and check your turkey often as you cook it. Pull it out just a bit shy of 165, cover it with foil, pour yourself a glass of wine, enjoy it, and THEN carve your turkey.
Happy Thanksgiving everyone!
