The cashew apple is the fruit of the cashew tree, known scientifically as Anacardium occidentale. It is a fleshy, pear-shaped structure that grows above the cashew nut, which is actually a seed. The cashew apple is typically yellow or red when ripe and is juicy and sweet, often used in beverages, jams, and desserts. While the cashew apple is edible, it is not as widely consumed as the cashew nut. It is rich in vitamin C and has a unique flavor that can be enjoyed fresh or processed. In some regions, it is also used to make fermented drinks and vinegar.
