Cocoa beans are actually seeds from the seed pod of a tree that grows in tropical regions. The tree produces a yellowish red fruit (pod) that contains a white fleshy pulp, which surrounds numerous seeds. As the fruit matures the pods are cut open to expose the pulp, allowing it to ferment so the seeds can be easily removed. The seeds are then dried by the sun or steam and are processed into chocolate, cocoa butter or cocoa powder.
Cocoa beans can be found in many health food stores including Whole Foods. You can also purchase them online at Amazon.com Truly Raw Whole Cacao Beans, Organic
