You can make your own very easily. Mix a big batch and fill a jar, or just use the ratios below to put directly in your recipe. For instance, if your recipe calls for 2 tsp. pumpkin pie spice, use double the amounts below. No need to stir them together first, either, just drop them in. If you have cinnamon but not all three of the others, you can leave one of them out and still be fine. (Just don't leave out the cinnamon!)
Pumpkin Pie Spice Makes 1 teaspoon.
1/2 tsp. ground cinnamon
1/4 tsp. ground nutmeg
1/8 tsp. ground ginger
1/8 tsp. ground cloves
Mix ingredients well.
