The true fruit of cashew is the kidney-shaped, greyish-brown nut (achene), which dries and does not split open. Inside the hard pericarp is a 2.5 cm long curved seed, the edible cashew nut. As the nut matures, the stalk (pedicel, receptacle and disc) at the base enlarges into the fleshy fruitlike structure, broadest at the apex, popularly known as the fruit (cashew apple). This thin-skinned, shiny, red or yellow, edible cashew fruit has a light yellow spongy flesh, which is very juicy.
