Cashew (Anacardium occidentale) is a popular edible nut native to Brazil and now cultivated widely in tropical regions such as India, Vietnam, and Africa. It grows on the cashew tree, which produces both the cashew nut and the cashew apple. The nut is kidney-shaped, encased in a hard shell containing caustic substances that are removed through roasting or steaming.

Cashews have a rich, buttery flavor and a creamy texture, making them a favorite snack and ingredient in sweet and savory dishes worldwide. They are valued not only for their taste but also for their high nutritional content, including healthy fats, protein, vitamins, and minerals. Cashews are also processed into cashew butter, cashew milk, and used as a dairy alternative in vegan recipes.
