This recipe makes the best brisket ever!  Kay Thistlewaite gave me the recipe. I cook with the fat side up so the marinade is absorbed into the meat as the fat melts. Leftover portions freeze very well, too, so this is a great make-ahead meal.I have prepared this brisket a lot since we lived in Chillicothe, Missouri, so many years ago. It’s nice because you can prepare it in advance and simply warm when you’re ready to serve.
