Cinnamon is an aromatic, spicy, warm-flavored spice made from the inner bark of several tree species from the genus Cinnamomum. It is harvested mainly by cutting the outer bark, which is later dried. Cinnamon is used primarily as a flavoring in sweet and savory foods and drinks; it is best known as the flavoring additive in spicy pies, tea, fruit cakes, and cinnamon rolls.
