Cinnamon (Cinnamomum verum, synonym C. zeylanicum) is a small evergreen tree belonging to the family Lauraceae, native to Sri Lanka, or the spice obtained from the tree's bark. It is often confused with other, similar species and the spices derived from them, such as Cassia and Cinnamomum burmannii, which are often called cinnamon too.
Cinnamon bark is widely used as a spice. It is principally employed in cookery as a condiment and flavoring material. It is used in the preparation of [chocolat]e, especially in Mexico, which is the main importer of true cinnamon. It is also used in the preparation of some kinds of desserts, such as apple pie, donuts, and cinnamon buns as well as spicy candies, tea, hot cocoa, and liqueurs. True cinnamon, rather than cassia, is more suitable for use in sweet dishes.
In the Middle East, it is often used in savory dishes of chicken and lamb. In the United States, cinnamon and sugar are often used to flavor cereals, bread-based dishes, and fruits, especially apples; a cinnamon-sugar mixture is even sold separately for such purposes. Cinnamon can also be used in pickling. Cinnamon bark is one of the few spices that can be consumed directly. Cinnamon powder has long been an important spice in Persian cuisine, used in a variety of thick soups, drinks, and sweets. It is often mixed with rosewater or other spices to make a cinnamon-based curry powder for stews or just sprinkled on sweet treats (most notably Shole-zard Persian شله زرد).
