Call it stuffing or dressing, they are actually the same. It just depends on where you cook it. Stuffing is cooked inside the poultry cavity. Dressing is cooked outside (on the side) of the poultry. This recipe is cooked on the side. Therefore, it is called "dressing".
This dressing is slightly moist. If you prefer a dry dressing reduce the 1/2 cup milk in the dressing ingredients to 1/4 cup. If you like an extra moist dressing try adding an extra 1/4 cup milk to the dressing ingredients.
