Cherimoya

Where: Peru

Mark Twain called this "the most delicious fruit known to men". Certainly, that's a hell of an endorsement he gave to this oddly shaped Peruvian fruit.

Found at a local Meijer, it took several days for it to ripen in a paper bag until it was soft, like an avocado, during which time I daily inspected it to see if it was ripe, and Katrina pointed out it didn't quite seem there yet.

Finally, it softened, and we cut it in half to dig in. The inside was quite odd, with a feathery, almost custard-like texture, and filled with large, black seeds. The flavor was mild, almost faintly tasting of lychee and papaya, but really I struggle to compare it to any other fruit I've had in texture of taste.
