Pure Ceylon Cinnamon Powder — 200g Square Tin

Usually not. Most supermarket cinnamon is cassia (Cinnamomum cassia or related species), a different plant with a single thick, hard layer of bark. Ceylon cinnamon is Cinnamomum verum, and its quills are formed from many thin layers of inner bark rolled together - which is why they are brittle and can be crushed by hand.

Keep the quills whole, in an airtight container, away from light, heat and moisture. Whole quills hold their aromatic oils far longer than ground cinnamon, so grinding only what is needed preserves aroma. Do not refrigerate - condensation is the main risk to dried bark.
