Cashew apples are the little-known counterpart to the cashew nut. Actually the “nut” is the botanical fruit, and the “apple” is just an accessory fruit. Technically, the cashew apple is not even a botanical fruit, since the cashew nut contains the seed.
Cashew apples are rarely eaten outside of placed where cashews are produced because the fruits are delicate, easily bruised, and have a very short shelf life. They are definitely culinary fruits though, as they are quite sweet and juicy, if astringent.
