I like to make all beef/pork gravy with cornstarch and water. Only use flour and milk when making fried chicken gravy. My son was married and living away from home before he knew meat loaf was supposed to be sliced and not spooned out of the pan. Does that tell you something about my cooking? Other than that I used to be a pretty good cook but couldn't for the life of me make a slicable meatloaf.
