04When the meat is fork-tender, remove the roast from the oven and carefully transfer the roast to a serving platter. Cover loosely to keep warm.05Skim off as much of the fat from the surface of the cooking liquid as possible. Reserve 2 tablespoons of the fat in a small bowl and add the flour. Stir to make a smooth paste. Add 1/2 cup of the hot cooking liquid to the bowl and whisk to combine. Slowly whisk this mixture into the hot cooking liquid that remains in the Dutch oven and place over high heat on the stovetop. Cook, whisking frequently, until mixture comes to a boil and thickens. Continue to cook for about 5 minutes, or until the sauce is thick enough to coat the back of a spoon and any floury taste is gone. Taste and adjust seasoning, if necessary.06Serve the roast with the hot gravy.
