A kidney-shaped nut that grows out from the bottom of the cashew apple. The shell is highly toxic so great care is taken in shelling and cleaning the nut. Cashew nuts have a sweet, buttery flavor and contain about 48 percent fat. Because of their high fat content, they should be stored, tightly wrapped, in the refrigerator to retard rancidity. As with most nuts, roasting cashews brings out their nutty flavor. See also nuts.
