Half-core a handful of apples. Don't take out the bottoms: if you do, the apple will fall apart. Stuff the core-holes with raisins and walnuts. Add about an eighth-teaspoon of cinnamon and nutmeg to the raisin-walnut mix in each apple. The raisins will plump as they cook, so don't overstuff the holes. Bake at 350 for 45 minutes.
