Does stuffing cooked inside the turkey taste better?
No, not necessarily. Stuffing cooked separately can be just as delicious. And it is safer because if you stuff the turkey there is a risk that the internal temperature of the stuffing will not reach a safe bacteria-killing temperature which is 165 degrees or higher. The unstuffed turkey will also cook faster reducing the risk of dried-out, overcooked meat. Using the pan drippings in the stuffing (dressing) will enhance the flavor too.
