I understand putting the turkey in a bag, but putting the stuffing in a bag in a turkey in a bag? Seems like overkill. Besides, don't the turkey juices flow into the stuffing anyway? I used to use these until one time the edge of the bag touched the side of the oven and it began to smoke. It emitted some really noxious fumes that hung in the air for hours! I figured at least some of that had to be leaching into the food. :P
Besides, ever since I learned how to brine a turkey, I don't need these!
