Notes
If you want to make a larger batch of this apple pie spice mix to keep on hand, it's very easy to just double or triple the ingredients.
Keep the jar of spice mix tightly covered in your pantry or spice cupboard for up to 1 year. Spices can be kept much longer, but they'll gradually lose their potency and flavor over time.
