Preheat oven to 350 ℉. Spray a roasting pan or the same Dutch oven you used to cook the brisket with PAM, or line the pan with parchment paper. Place brisket into this pan. *Parchment paper is great, because the sugar in the crust can be hard to get off the bottom of your pan!
Mix Dijon mustard, brown sugar and soy sauce and spread over the entire brisket – the top and all sides. Cover this mixture with a generous coating of Peppercorn Perfection and pat over the entire top and sides of the brisket, patting the pepper blend into the mustard mixture so it will adhere.
Alternatively, for a more sugary-pepper crust, mix only the mustard and soy sauce, and spread over brisket. Then, mix the sugar with the Peppercorn Perfection and pat the combination into the mustard mixture, covering the entire top and sides of the brisket.
Bake at 350 F for 30 minutes or until crusty and browned on the outside. Remove from oven and allow to sit for about 5 minutes before carving. Slice across the grain into ½ inch thick slices. Serve with champagne vinaigrette cabbage, roasted potatoes, and Brown Sugar-Dill Braised Carrots.
