The cashew is in the family Anacardiaceae. Its English name derives from the Portuguese name for the fruit of the cashew tree, caju, which in turn derives from the indigenous Tupi name, acajú. It is now widely grown in tropical climates for its cashew nuts and cashew apples.
The cashew nut is a popular snack, and its rich flavor means that it is often eaten on its own, lightly salted or sugared. Cashew nuts are sold covered in chocolate, but less often than the cheaper peanuts and almonds.Groundnut
Cashew nuts also factor in Thai cuisine and Chinese cuisine, generally in whole form, and in Indian cuisine, often ground into sauces such as shahi korma, and also used as garnish in Indian sweets and desserts.
The cashew nut can also be harvested in its tender form, when the shell has not hardened and is green in color. The shell is soft at this stage, and can be cut into two with a knife.

This is mostly found in Kerala cuisine, typically in the avial, a dish that contains several vegetables, grated coconut, turmeric and green chilies.
