I've had many turkeys over the years that decided they wanted to be finished cooking an hour or more before I needed them to be. Normally you want your turkey to rest for 20 minutes before serving but if your turkey has finished cooking an hour early or you need to transport it, simply tent the entire turkey well in foil, sealing the pan and the turkey inside so it's as airtight as you can. Next, place a large clean bath towel over the top of the foil. This will help to hold the foil down and keep it insulated. Now the turkey will remain warm and lock in the moisture so that it doesn't dry out before serving time.
