Chocolate comes from the fruit of the Theobroma cacao tree, whose name means "food of the gods" in Greek, an apt name for the most popular sweet treat in the world. Theobroma cacao is native to the Amazon and Orinoco river basins in South America. These tropical trees thrive in hot, humid places within about 20 degrees of the equator. Growers have established plantations in other regions including West Africa and Southeast Asia. Today, Ghana, Côte d'Ivoire, Nigeria, Indonesia and Brazil, to keep up with the growing demand for the sweet commodity.
Cacao trees bear fruit that contains up to 50 seeds, or beans. Harvesting cacao seeds is done by hand because machines could injure the precious trees. Workers remove the pods when ripe, and open them with a machete. The seeds are placed in large fermentation trays that are stacked and covered in banana leaves, where they are left for two to seven days. The fermentation process produces the chocolate flavor and aroma.
The fermented beans are then dried out in the sun. Workers turn them several times a day for three to five days to complete drying. The beans are then taken to the chocolate factory, where they are cleaned and debris is removed.
The beans are roasted in large, rotating ovens. Roasting draws out the cocoa flavor of the beans. After roasting, the beans go into a winnowing machine, which cracks the beans and removes the hulls. The remaining part of the bean is the nib, which then becomes the chocolate.
The nibs are ground under a series of rollers, and eventually turn into a thick paste called chocolate liquor. This paste does not contain alcohol – that would be chocolate liqueur. Chocolate liquor is the main source of unsweetened baking chocolate.
At this stage, the makers determine the type of chocolate being produced. The following are the types of chocolate:
