Custard apple is a common name for a fruit, and the tree which bears it, Annona reticulata.

The fruits vary in shape, heart-shaped, spherical, oblong or irregular. The size ranges from 7 to 12 cm (2.8 to 4.7 in), depending on the cultivar. When ripe, the fruit is brown or yellowish, with red highlights and a varying degree of reticulation, depending again on the variety. The flesh varies from juicy and very aromatic to hard with a repulsive taste.^[3] The flavor is sweet and pleasant, akin to the taste of 'traditional' custard.
