Cinnamon is a popular spice in baked goods. It is made from the inner bark of a tree. Cinnamon bark has an antioxidant capacity of about 77 millimoles per 100 grams.

Cinnamon has a warm, slightly spicy, and sweet taste. You can add it to baked foods, oatmeal, yogurt, stews, hot chocolate, and tea. 

Spices are often available whole or ground. Opt for whole spices and grind them in small amounts when you use them. This is because ground spices quickly lose their aroma and flavor. You can store spices at room temperature for about two years, and even longer if they are whole.

Store spices away from heat, sunlight, and moisture to keep them fresh longer.
