I learned this from Bobby, my ex. One year, when my foot had been run over and I was confined to bed, I couldn't cook our Thanksgiving dinner. So Bobby did it. I went into the kitchen just in time to see him putting the turkey in the oven upside down. I started laughing and told him that he would have to turn it over. He refused, insisting that he always cooked a turkey that way. It turns out he was right.
About halfway through the cooking process (when the skin on the bottom starts to brown) you flip the turkey over. Then you finish cooking it. It comes out golden brown (on both sides) and the breast meat is NEVER dry! I don't even use aluminum foil over it anymore. I have a perfect turkey everytime.
