Today we refer to the cashew as a nut, but it’s actually a seed. Grown at the bottom of a delicate, pear-like fruit, cashew’s closest relatives include mangos and pistachios. And even though cashews are cultivated inside an extremely protective, honeycombed shell, they are the only nuts marketed exclusively without their shells.
Originally spread from Brazil by Portuguese explorers, international trade of cashews began in the 1920s. Now cashews are grown all over the world.
