Cinnamon is a flavorful spice that comes from the bark of a tree. The tropical tree that produces the spice is also called cinnamon.
Cinnamon is a common spice in sweet baked goods like cinnamon rolls and coffee cake. It's also used in savory dishes, particularly in Middle Eastern and North African cuisine. While most people are familiar with the dark reddish-brown ground cinnamon you can shake on your cinnamon toast, it also comes in the form of a short, rolled stick. The Latin source is cinnamum, which was once a term of endearment, as well as the name of the spice.
