Nov 6 2008 Many people believe that the difference between stuffing and dressing is how you cook it. If you cook it inside the turkey it's called stuffing; if you cook it outside it's known as dressing. However, it may be a regional thing: apparently in the South it's always called dressing. I've always referred to it as stuffing whether it's cooked inside or outside the bird. What do you make? Do you cook it inside or outside?
