Preheat oven t 350°F. Salt your brisket and put it fat side down in the roasting pan. Layer the onions and apples around the brisket. Pour the onion soup on top of the brisket. Add the cider and white wine until it is about an inch up the brisket. Cook 20 minutes per pound. Cover with foil for 3/4 of the cooking time. Cook the rest uncovered. Allow to rest. Enjoy with noodle pudding and red cabbage. Bon Appetit.
