Need ID for large yellow fruit
A family member found this large yellow fruit under a 15 foot tree near his neighborhood in Atlanta, GA. It is near a house that is apparently unoccupied, so there is no one to ask about the tree. There were 20 to 30 such fruit on the ground under the tree, and 2 or 3 still attached on December 15. He and I thought it might be a large paw paw, but the inside is not compatible. The fruit is firm, about the feel of a large unripe pear. It has a distinct fruity sweet odor, similar to a mango. The flesh is firm, like a green apple. The taste is tart, but not at all sweet. The seeds are small and numerous, and are arranged in stacks inside four long cavities around the center axis of the fruit. I am stumped! Anyone recognize it?
