Never had it.  Want.

The heart-shaped fruit tastes like some seriously all-American apple pie, but looks distinctly prehistoric, with a green, bumpy peel. The creamy white inside is dotted with large black seeds, as if an apple has received a tropical makeover. To eat one of these bad boys simply slice it in half and dig in with a spoon. If ever there was an inspiration for kitchen-crafted custard, this is it. For a particularly pleasant twist, scoop the insides out of the leathery shell, freeze them and eat as an alternative to ice cream.

Never even heard of it. Almost sounds made up.
