Chocolate is a food product made from roasted and ground cacao pods, that is available as a liquid, solid or paste, on its own or as a flavoring agent in other foods. Cacao has been consumed in some form since at least the Olmec civilization, and the majority of Mesoamerican people - including the Maya and Aztecs - made chocolate beverages.
The seeds of the cacao tree have an intense bitter taste and must be fermented to develop the flavor. After fermentation, the beans are dried, cleaned, and roasted. The shell is removed to produce cocoa nibs, which are then ground to cocoa mass, unadulterated chocolate in rough form. Once the cocoa mass is liquefied by heating, it is called chocolate liquor. The liquor may also be cooled and processed into its two components: cocoa solids and cocoa butter. Baking chocolate, also called bitter chocolate, contains cocoa solids and cocoa butter in varying proportions, without any added sugar. Powdered baking cocoa, which contains more fiber than cocoa butter, can be processed with alkali to produce dutch cocoa.
