Cocoa powder, an unsweetened chocolate product, adds deep chocolate flavor to desserts and beverages. Cocoa powder occurs when the fat, called cocoa butter, gets removed from the cacao beans during processing. The leftover dried solids get ground into the product sold as cocoa powder.
Dry cocoa solids are the components of cocoa beans remaining after cocoa butter, the fatty component of the bean, is extracted from chocolate liquor, roasted cocoa beans that have been ground into a liquid state.
