I always thought stuffing and dressing were the same except “stuffing” was cooked in the bird and “dressing” was cooked in a dish. In my mind, I had servings of both stuffing and dressing today—some from inside the bird and some from a Pyrex dish.
In my experience w/ the Chicago Italians: stuffing is loaf bread and is very wet. Dressing is cornbread and biscuits, and much drier. I suppose different families make each differently, but I can not eat her stuffing!!! By definition stuffing is stuffed in the birds; however, it too can be done in a casserole dish. This does not change the fact that it is not edible to my Southern taste buds.
