Though this fruit has come up in a few discussions (such as here, here, and here), there doesn’t appear to be a general discussion thread about this species. There’s also some disagreement as to whether to call it D. digyna or D. nigra, and I haven’t been able to figure out which is the more accepted. And, as Richard wisely pointed out in a recent discussion, the poisonous D. revoluta is not the same species, despite sharing a common name (so don’t eat that one).
My history with the black sapote goes back to my childhood in Miami, where I grew up in poverty and food-insecure. A significant part of my diet was urban-foraged fruit, especially things that many people in Miami grow but never harvest, leaving piles of rotting fruit on their lawns. While I ate all sorts of things, I sought out most of all the “filling” or “hunger satiating” things. I knew the location of a number of large-but-neglected avocado, mango (you would be shocked how many people in Miami treat their mango trees like a nuisance rather than food source), mamey, sapodilla, and black sapote trees. Each had their place, but in many ways black sapote was my favorite of the lot (ripened when few things did, very filling, nice smooth texture to eat with a spoon, can be more flavorful when fully tree ripened). I also knew the owner of the main tree I visited, and he begged me to eat as many as I could because he hated cleaning up the mess of the tree.
In retrospect, it’s not really a top tier fruit, but for me it’s nostalgic, and for anyone who has the space to grow this (huge) tree, it is a very good famine food. Here’s the UF guide for the species, which has some great info:

And I’ll finish with a photo of one of the seeds I’m starting in my greenhouse:
This is my first attempt to grow this species here in Seattle, which I’m planning to try to hybridize with D. texana. I’ll be keeping it in a container, perhaps grafted on texana seedlings, if they prove to be compatible, since I suspect that would have a dwarfing effect.
