I usually cook a 14 pound turkey unstuffed at 325 or 350 and it cooks
in 2 1/2 hours.

This year I decided to try something different and stuff the turkey
with aromatics; I quartered an onion, and cut an apple, orange, lime
and lemon into wedges and stuffed the turkey with that. I was worried
that the juices which rendered in the cooking bag would taste like
citrus juices and not turkey juices, but they did not and the gravy I
made from the drippings was delicious. It took a lot longer to cook
this year, maybe 3 1/2 hours but the turkey was very moist and
delicious. Needless to say when I removed the turkey from the bag I
discarded the fruit and onion.
