Did you ever wonder why you never see cashews sold in their shell? Well, recently, while I was reading one of my favorite trivia books, Amazing... But False!, by David Diefendorf, I learned why. Interestingly, cashews are the seeds that grow on the tip of the cashew apple which grows on trees in places like Brazil and India. The cashew seed is grown with a coating on the outside called cardol, which is an irritating and pungent oil. Because of this, humans can not remove the coating, so it has to be done by machines. After that, to be certain that there is no more cardol left, the cashews are roasted.
