Annona cherimola

The cherimoya (Annona cherimola), also spelled chirimoya and called chirimuya by the Quechua people, is a species of edible fruit-bearing plant in the genus Annona, from the family Annonaceae, which includes the closely related sweetsop and soursop. The plant has long been believed to be native to Ecuador and Peru, with cultivation practised in the Andes and Central America, although a recent hypothesis postulates Central America as the origin instead, because many of the plant's wild relatives occur in this area. Cherimoya is grown in tropical and subtropical regions throughout the world including Central America, northern South America, Southern California, South Asia, Australia, the Mediterranean region, and North Africa. American writer Mark Twain called the cherimoya "the most delicious fruit known to men". The creamy texture of the flesh gives the fruit its secondary name, the custard apple.
