Cinnamon: Cinnamon refers to CinnamomumVerum or ‘true cinnamon,’which is a plant endemic to Sri Lanka. Most other cinnamon (from other countries) is from related species of plants and is called ‘cassia’. It is a spice obtained by making shavings (also known as quills) of the inner bark of the cinnamon plant. Cinnamon trade has a very long history and records show cinnamon in the spice trade of Egypt as early as 2000BC.
