Meanwhile, add the Poire Williams to the skillet and boil for about 3 minutes, scraping up any browned bits from the bottom. Add the cider and bring to a boil. Add the apple slices, cover and simmer over low heat, turning once, until the apple slices are translucent, about 5 minutes. Uncover and simmer until the cider has reduced to a syrup. Spoon the apples into shallow bowls and top them with the pear wedges. Dust with cinnamon and serve with whipped cream.
