My most favorite autumnal flavor is hot spicy apple pie with vanilla ice cream melting all over it. The spiciness with the apples and cinnamon all mixed together with the crunchiness of the pie crust is just mouth watering to me. The smell filling my house as it bakes is just out of this world.
Then when the pie sits just briefly to cool but not completely cool, sliced, and then a piece is smothered with the delicate vanilla flavor of ice cream as it melts. Oh what a foodgasm!
