Ceylon cinnamon is a dried spice, so it can be found in your local grocery store’s spice aisle all year long. If you want to be sure that you are getting Ceylon cinnamon and not cassia cinnamon, you may need to visit a specialty spice shop, however, since these spices aren’t generally differentiated in the US. Ceylon cinnamon can be used in both stick and ground form. Cinnamon is equally potent in either form, and ground cinnamon is much easier to add to most dishes. Keeping your cinnamon in an airtight container can help keep it from losing its flavor.
