Remove the turkey from the pan and let rest for 10 minutes covered with aluminum foil. Place the pan back on the stove. Add the demi-glace sauce and the remaining fresh cranberries to the pan juices. Stir to combine and reduce for about 2 minutes. Adjust the seasoning. Place the roast on a large platter and serve with the cranberry and port wine sauce. You can garnish with pomegranate seeds and sage leaves.
