Ok. It just looks unripe to me...whatever it is...I can see where that could be a (very) thick skin. I hope ya'll figure it out and what to do to get it edible. Could it be some type of ornamental? Osage orange (your bush isn't osage orange) produces a "fruit" of sorts...big "oranges" but they're not fit to eat and really just make a mess (great firewood and fenceposts, though!
).
Keep us posted.
