The cashew fruit (Anacardium occidentale) is an agricultural product which consists of two distinct parts, a fleshy stalk in the form of a pear, also called cashew apple, with a brilliant yellow or red skin, and a nut of grey-brownish colour, in the shape of a kidney, which hangs from the lower end of the stalk or apple. For this read, we’ll be looking at some cashew by products, how they come about and why you should probably consume them.
The mature cashew apple can be eaten fresh, cooked in curries, or fermented into vinegar, as well as an alcoholic drink. In many countries, particularly in South America, the cashew apple is used to flavor drinks, both alcoholic and nonalcoholic. Lets take a look at some cashew by products.

Cashew nut is made up of a fruit in which the kernel is embedded. The real fruit of the cashew is commonly a nut. It is a kidney- or heart-shaped achene, in any normal variety.
Its color varies from bottle green to grayish brown (dried fruit). It is attached to the end of a fleshy footstalk or peduncle, which is in fact the receptacle of the flower, that is, broadened and swollen, and forms the false fruit.
From the cashew plant, you can get oil from the cashew nuts or from the cashew shell. Cashew nut oil is a dark yellow oil derived from pressing the cashew nuts (typically from lower value broken chunks created accidentally during processing), and is used for cooking or as a salad dressing. The highest quality oil is produced from a single cold pressing.

The cashew shell oil is a natural resin with a yellowish sheen found in the cashew nutshell, and is a byproduct of processing cashew nuts. It should not be confused with the edible cashew nut oil, as it is a strong irritant. It is therefore a danger in small-scale processing of the shells, but is a raw material having multiple possible uses. It is used in tropical folk medicine and for antitermite treatment of timber.
