The best way to thaw a frozen turkey is to let it slowly defrost on a tray in the refrigerator for 3 to 4 days (24 hours for each 5 pounds of turkey). If you must thaw a turkey in a hurry cover the turkey with cold water and change the water frequently (every 1/2 hour per pound of turkey). As soon as the turkey is thawed, refrigerate it or begin preparing it for cooking. For maximum eating quality, don't refreeze uncooked turkey meat.
