Cashews are seeds of a tree that is native to Africa and South America. Today though, most cashews come from India. The shells are kidney shaped and grow in a double shell at the top of a pear shaped fruit. Cashews are always sold without their shells because their shells contain a caustic oil that is related to poison ivy. The nuts must be carefully extracted so they do to come into contact with the oil.

Cashew nuts are well-known kidney-shaped nuts that are light-colored, delicate in flavor, and slightly spongy in texture. Cashew nuts belong to the same family as the mango and pistachio nut (Anacardiaceae). They are actually seeds that adhere to the bottom of the cashew apple, the fruit of the cashew tree (Anacardium occidentale). Cashew apples are regarded as delicacies in Brazil and the Caribbean.
Cashew nuts in the shell are not available in stores since the interior of their shells contains a caustic resin known as cashew balm. This resin, which is toxic, must be removed before they are fit for consumption. Cashew balm is used in varnishes and insecticides.
Doreen Rodo, Nutrition & Dietetics, answeredCashews are the "fruit" of the cashew tree. They are popular in Thai and Chinese cooking, but they also make a great snack. Cashews are a good source of iron, manganese, magnesium and zinc. They contain fiber and healthy fats. The serving size is 1 oz, which is a small handful.Helpful? 1 person found this helpful.
