Yes and its a dying art, even KFC is putty yucky brown gravy on their mashed potatoes? with fried chicken? Its a Yankee plot to overturn the old South. My wife however is the mashed potato queen, they really don't need milk gravy, but with its addition they nearly float off the plate into your mouth, actually pour the grease off the chicken fryer, or the chicken fried steak, the small pieces of breading in the gravy give it additional flavor and texture.
Now real Southerners also make red-eye gravy with the skillet leavens of a Tennessee Smoked Ham, not in the same league. I think I must be half yankee, cause thats way to SALTY and no where close to my wifeys mashed potatoes and gravy! Billy
