In a bowl, place the 6 tablespoons ground cinnamon, 2 tablespoons ground ginger, 2 tablespoons nutmeg, 2 teaspoons ground allspice, and 2 teaspoons ground cloves and whisk very well to combine. Transfer to a spice jar or a glass jar with a tight-fitting lid and store in the pantry for up to 1 year.
Notes
Use fresh spices. Since this recipe is all about the flavor of the individual spices, make sure your ground spices are fresh and fragrant. Older spices can taste flat or dusty. Spices should be discarded within a year of purchase!
Adjust the blend to taste. Prefer more cinnamon or a little less clove? Feel free to tweak the proportions to suit your taste.
Spice substitutions. I am huge fan of cardamom and love to add it into this blend. Sometimes I'll substitute the ginger completely for cardamom, or use 1 tablespoon of ginger and 1 tablespoon of cardamom. You can experiment with other spice proportions as well. Sometimes I'll add a big pinch of ground black pepper!
Make a bigger batch. This recipe is easy to double or triple, especially during pumpkin season when you'll likely be using it often.
Label the jar. Add the date and the name of the blend to your jar so you know what you've made and when.
Store it properly. Keep your pumpkin spice blend in an airtight jar or container in a cool, dry pantry. For the best flavor, use it within one year.
