Cashew nuts are actually seeds that adhere to the bottom of the cashew apple, the fruit of the cashew tree, which is native to the coastal areas of northeastern Brazil. Cashew apples, while not known in the U.S., are regarded as delicacies in Brazil and the Caribbean. The seed we know as the kidney-shaped cashew "nut" is delicate in flavor and firm, but slightly spongy, in texture.
