Ground cinnamon may be among the most popular and widely known spices. Cinnamon itself is derived from the inner bark of several trees of the cinnamomun genus, and is ground and packaged in the little jars you see on the supermarket shelf. It is widely available in the spice aisle of the supermarket.
While cinnamon is commonly found in sweet dishes such as cakes, desserts, sweet breads, and cookies, it is also found in many savory dishes especially in middle eastern cuisine.
Cinnamon comes in handy in low calorie cooking because it can lend a sweet flavor to foods where the sugar has been cut in order to save on calories.
