Cocoa is a misspelling of cacao that appeared on a ship’s manifest in the 18th century and led to the replacement of the original word with the erroneous one. The “beans” are the seeds from the pod, or fruit, of the Theobroma cacao tree. At the center of the bean is the nib, from which chocolate is made. There are three species of bean—Criollo, Forastero, and Trinitario—and many subspecies. More than 13,000 clones of cacao have been classified.
