Did you know that the ancient Mayans and Aztecs used cacao beans in their cooking? The beans were held in high regard because of their health benefits and were even used as currency. Cocoa beans contain phenols which contain those oh-so-wonderful antioxidants, and you know what? The less diluted your chocolate, the better it is for you.
You can order cocao nibs from a variety of places. Prices generally range from about $3.99 to $116.00 depending on quality. Grind them, and be like an Ancient Aztec: use them in your chili!
