We have both heard it and we both don't get it! Why do some people call stuffing, "dressing?" See what we did there? As if it is our word being called something else. Truth is, some would think we are weird for calling it "stuffing" at all!
Well, as with most conundrums we encounter here, we had to do our research to get to the bottom of this!
According to Food & Wine Magazine, there is a regional factor, but the technical answer is this: If it is stuffed in the bird, it is STUFFing; if it is baked in a pan, it is dressing.
We don't know, dressing just doesn't make sense even if it is in a pan. Now if it were adorning the bird, that would be a better argument. As for stuffing, come on, you stuff it in the bird...and then you stuff it in yourself! Who could argue with that?!
