People, this thing was good. Peel it, get the seeds out--they are large, dark seeds, detached from the flesh, easy to get out--and eat the bits that ensue. So pleasant. It tasted like something I had as a child, but I can't think what. (C.S. Lewis would probably think that meant it tasted Platonic in some form; never mind C.S. Lewis. This is a Mark Twain fruit. All the webpages say so.) markgritter suggested that it tasted like the actual fruit form of Fruity Pebbles, and Timprov suggested the actual fruit form of white LifeSavers before going on to propose that the cherimoya is the answer to what fruit "fruit flavoring" is supposed to taste like.
This has more depth and complexity of flavor than "fruit flavoring," much less those other nasty things. Highly recommended. Go get yourself one.
