      Thanks for introducing me to another food of which I was unfamiliar. I have never seen a water apple for sale in any of our local markets. It certainly is pretty. It would be fun to be able to taste one someday.

      We have one of these trees here in our garden in Brazil. Although it has been here for at least 8 years, it still isn't producing. I think it needs some TLC.

      However my friend has one and it is huge and produces fruit like crazy. They also have such beautiful flowers, that the hummingbirds love. I have often gone to her home and returned with a big bag full of them.

      I normally eat them raw or make them into a jam.

      After reading this, I am inspired to sort my tree out.

      I'm happiest when I see fruits I recognise; they bring back my childhood memories. We called this 'cushoo.' in Grenada, and I ate a lot of it.

      Nice Hub on its benefits, Bro. Well done!
