Annona reticulata L. - syn. Annona lutescens Saff. - Annonaceae
bullock's-heart, bull's heart, custard apple, Netzannone, Ochsenherz
Evergreen tree, possibly native to Central America and the Caribbean, cultivated in tropics.
„The flesh varies from juicy and very aromatic to hard with a repulsive taste. The flavor is sweet and pleasant, akin to the taste of 'traditional' custard.“ http://en.wikipedia.org/wiki/Annona_reticulata
„Volatile compounds were isolated from four cultivars of bullock's heart fruit (Cenizo, Rojo, Verde, and De Ojo) by simultaneous steam distillation - solvent extraction. Compounds were identified by HRGC and capillary GC-MS. One hundred and eighty compounds were identified in the aroma extracts, of which α-pinene, β-pinene, myrcene, limonene, terpinen-4-ol, and germacrene D were found to be the major constituents. Fruit from cv. De Ojo containing the highest concentration of total volatile and the highest major terpenoid content had the highest custard-like and overall fruity aroma intensity. The presence of many terpenic compounds is thought to contribute to the unique flavor of the bullock's heart fruit.“
