Combine salt, ginger, nutmeg and cinnamon; rub over roast. Place roast, fat side up, on a rack in a shallow roasting pan. Insert a thermometer. Bake, uncovered, at 325° for 2-1/2 hours or until thermometer registers 160°. Cover and let stand 15 minutes before slicing.
In a medium skillet, combine the first six spiced apples ingredients; bring to a boil. Reduce heat and simmer, uncovered, until slightly thickened. Add apples; simmer, uncovered, until apples are just tender, stirring gently. Serve with sliced pork roast.
If Cooking for Two: Both the pork roast and apples freeze well (separately). Store individual portions in airtight containers.
