A medium-sized, large-leaved tree native to rainforests from the Malay Peninsula to Sumatra, Java and Borneo. The attractive, round, thick-skinned, white fruits are slightly larger than a ping pong ball and have translucent white flesh with a sour but refreshing taste. They can be made into a nice, refreshing drink with added water and a sweetener. The unripe skin is used in local cooking to add a delicious sourness. The tree is quite rare in the forest where it is found on more fertile soil. When loaded with bunches of fruit it is a spectacular sight.
