Pumpkin and vanilla were meant for each other. Ditto with all the spices in this incredibly light, moist, delicious cake. Really, what could say autumn better than a freshly baked Pumpkin Chiffon Cake, a Pumpkin Pie or Pumpkin Spice Latte? Over the years I’ve really come to appreciate really fresh spices. I grate my nutmeg and grind allspice and cinnamon in a coffee grinder dedicated just for spices. The flavors really pop when they’re fresh. And our dear vanilla is the backup chorus once again, making sure all the flavors work synergistically.
