Cinnamon is a spice obtained from the inner bark of several tree species from the genus Cinnamomum. Cinnamon is used mainly as an aromatic condiment and flavouring additive in a wide variety of cuisines, in particular sweet and savoury dishes such as biscuits, breakfast cereals, snack foods, bagels, teas, hot chocolate, and traditional foods. The characteristic aroma and flavour of cinnamon derive from its essential oil and principal component, cinnamaldehyde, as well as numerous other constituents, including eugenol.
