It's "pumpkin PIE spice" not "pumpkin spice." And yes, not sure when it started (maybe with Starbucks Pumpkin Spice lattes?) but every October we are now subjected to all things pumpkin pie flavored in the US. Pumpkin Pie Spice is a blend of nutmeg, cinnamon, ginger and cloves - these are the spices that make pumpkin pie delicious. Pumpkin alone? Bland.
