How do you slow down the cooking of your turkey?

Answer 1

I asume you mean the turkey is cooked on the outside but raw in the middle, cover the bird with foil to stop the skin burning, add some water to the roasting pan to create steam which will help keep the bird moist, turn down your oven, then slowly cook the turkey until it is done.

Answer 2

You should reduce your temperature. If you have a high temperature, the turkey will burn on the outside and not cook on the inside. It will also take your turkey longer to cook but it will be more tender and juicer and have a better flavor.
