Many cashew eaters may be surprised to learn about the origins of the popular nut. The nut comes from the cashew tree, a small evergreen tree in the flowering plant family Anacardiancese. Northwestern Brazil is the native home of the plant, but it is now cultivated in all regions with sufficient tropical conditions. India, Vietnam, and Brazil, in that order, are the largest producers of cashew nuts.
The cashew tree produces cashew flowers that yield cashew apples. These apples, better known in Central America as "marañón", are oval to pear-shaped and ripen into a yellow and/or red structure between 5 to 11 centimeters long. These apples are the tree's false fruit and look like oversized hot peppers or pears. The real fruit of the tree are the small kidney-shaped drupes that protrude from under the pseudo fruit, the cashew apples. In botany, a drupe is a type of fruit in which an outer fleshy part surrounds a shell of hardened endocarp, the pit or stone, with a seed inside. Hidden inside each drupe is the cashew flower’s single seed, a single cashew.
The seed, or cashew nut, is surrounded by a double shell containing a caustic phenolic resin, urushiol, a potent skin-irritating toxin also found in poison-ivy. The urushiol must be removed from the dark green nut shells before the seed inside is processed for consumption; this is done by shelling the nuts, a somewhat hazardous process, and exceedingly painful skin rashes among processing workers who come in contact with the toxin are common.
