The fruit is a large ellipsoid berry, 4-8 cm in diameter, very much resembling a smooth-skinned potato and containing 2-5 seeds. Inside, its flesh ranges from a pale yellow to an earthy brown color with a grainy texture akin to that of a well-ripened pear. The seeds are black and resemble beans, with a hook at one end that can catch in the throat if swallowed.
The flavor is exceptionally sweet and very tasty, with what can be described as a malty flavor. The unripe fruit is hard to the touch and contains high amounts of saponin, which has astringent properties similar to tannin, drying out the mouth.
