Annona × atemoya Mabb., Paradisus 143 1998. ; 

The atemoya, Annona × atemoya, is a hybrid of two fruits – the sugar-apple (Annona squamosa) and the cherimoya (A. cherimola) – which are both native to the American tropics.[1]

This fruit is popular in Taiwan, where it is known as the “pineapple sugar apple” (鳳梨釋迦), so is sometimes wrongly believed to be a cross between the sugar-apple and the pineapple. In Cuba, this fruit is called anón, and in Venezuela chirimorinon. In Palestine and Lebanon, the fruit is called achta. This is different from the Achta that is used in many Lebanese desserts, including ice cream, which is actually the skimming of fresh milk or cream.

An atemoya is normally heart-shaped or rounded, with pale-green, easily bruised, bumpy skin. Near the stem, the skin is bumpy as it is in the sugar-apple, but become smoother like the cherimoya on the bottom. The flesh is not segmented like that of the sugar-apple, bearing more similarity to that of the cherimoya. It is very juicy and smooth, tasting slightly sweet and a little tart, reminiscent of a piña colada. The taste also resembles vanilla from its sugar-apple parent.[2] Many inedible, toxic, black seeds are found throughout the flesh of the atemoya. [3] When ripe, the fruit can be scooped out of the shell and eaten chilled.[2] 

Atemoya (Annona cherimola × squamosa) was developed by crossing cherimoya (A. cherimola) with sugar-apple (A. squamosa).

The atemoya, like other Annona trees, bears protogynous, hermaphroditic flowers, and self-pollination is rare. Therefore, artificial, hand pollination almost always guarantees superior quality fruits. One variety, ‘Geffner’, produces well without hand pollination. ‘Bradley’ also produces fair crops without hand pollination, but the fruit has a habit of splitting on the tree.[4] Atemoyas are sometimes misshapen, underdeveloped on one side, as the result of inadequate pollination. An atemoya flower, in its female stage, opens between 2:00 and 4:00 pm; between 3:00 pm and 5:00 pm on the following afternoon, the flower converts to its male stage.

Another variety of Sour sap from Sri Lanka on the Kandy-Colombo road.
Picture is taken on the 18th of November,2010.

These seem to be Anona muricata, only difference may be that these are mature fruits and the spines seem to be broken and blunt.

These need to be ammended as Custard Apple & not Sour Sap.

I think this is Annona atemoya

This is really interesting. A new fruit.
Now I wish I had tasted it.
It does match with the images given in Google search.
Waiting for validation.
Thanks a lot.


These were seen in small fruit shops by the roadside.

Are these Soursap fruits or Custard Apples?


Thanks but ‘Yes’ for which one?
Soursap or Custard Apple?

Custard apple indeed! 

Yes; it is the Sita phal/custard apple-a slightly different variant.

Annona atemoya as per another thread.
