One year I had sprained my ankle and my husband had to cook Thanksgiving Dinner. He went to put the turkey in the oven and it was upside down. I tried to stop him but he told me he was cooking dinner and for me to leave him alone. So I did.
The turkey was perfect.
You cook it upside down until about the last 45 minutes or so, then you flip it. That way the breast meat is as moist as the dark meat usually is! Also the skin on the bottom is crisp and brown just like the skin on top.
A perfect Turkey everytime.
