I was told that these were Atemoya from Israel.  I naturally assumed Geffner as a possibility.  Can anyone help me identify if these are indeed Geffner or perhaps African Pride by chance?  Also, how do I know if these are ready to eat?  They're naturally on the lighter green side, so it doesn't appear that they have gotten any lighter in color.  These are all from the same tree, so I hope it will be helpful to identify.  Thanks for your assistance.









Here's also one of a supposed Dr. White seedling.  Although the leaves certainly look like a cherimoya (sorry no actual leaves in the picture), the shape of the fruit looks kinda atemoya-ish?
