Pumpkin spice, often called pumpkin pie spice, combines warm and aromatic spices such as cinnamon, ginger, nutmeg, allspice, and cloves. While variations of this blend may omit one or two spices, the essence of pumpkin spice typically includes a balance of at least two or three of these components: 4 parts ground cinnamon, 2 parts ground ginger, 1 part ground nutmeg, and 1 part ground cloves. If using allspice, add it in a 1 part ratio as well.
