Not to be confused with Pumpkin Spice Latte Day (August 24) or Pumpkin Day (October 26), this food holiday celebrate the spice that flavors autumn’s favorite drinks, desserts and holiday meals. Its smell is distinctive, but despite its name it contains no pumpkin; instead, pumpkin spice is a blend of spices including cinnamon, ginger, nutmeg, cloves and allspice used to flavor pumpkin pies.
