Please identify this fruit

[sapote]

My first thought was black sapote, but upon close it didn’t look like one.
It seems like someone had picked the fruits when they were ready -- saw the empty stems but nothing on the ground. Must be an edible fruit tree and the fruit to stem attachment point looks like magosteen and black sapote.

Black sapote. You can tell from the calyx

I also think its black sapote.

I think you're right. The more I look at the darken branches and the leaves, the more I think it's BS. I used to have a young tree with full of green fruits, not ripen yet and the cold winter down to 32F that killed it instantly on one night. I remember the fruits were different shape than in pic, but it was a long time ago so I must be wrong. Have never tasted a BSapote yet. One day I will get a fruit from this tree.
