Help, please! Can you identify this bitter fruit?
We visited Puerto Rico in early July. This fruit pictured was growing on a tree in a cultivated (landscaped) area. I tasted a minuscule amount and it was unbelievably bitter. The taste stayed on my tongue for an hour. Can you tell me what it is? I haven't had any success finding it. Birds seem to eat the inner brown part; the part I tasted was more from the light part nearer the outside, I think. This was the bitterest thing I've ever tasted! Thanks.
