It is produced from cocoa beans that have been fermented, dried, roasted, and separated from their skins. The beans are ground into cocoa mass (cocoa paste). The mass is melted to become the liquor, and the liquor is cooled and molded into blocks known as unsweetened baking chocolate (bitter chocolate).
Chocolate liquor contains roughly 53 percent cocoa butter (fat), about 17 percent carbohydrates, 11 percent protein, 6 percent tannins, and 1.5 percent theobromine.
