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.

@manatita, nice & sweet name cushoo. I just love its mild flavor and the crunchiness. Appreciate your visit my friend.

Hi Rajan jolly you shared a worthy hub. The interesting facts about a unique fruit.
Mary Wickison from Brazil on April 04, 2016:
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.
Dora Weithers from The Caribbean on April 04, 2016:
I know these apples but have only seen them in red. What a phenomenon! I always learn something new when I read you. Thanks for the birthday wishes!
manatita44 from london on April 04, 2016:
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!
Bill Holland from Olympia, WA on April 04, 2016:
Never heard of it. It looks like a pepper. I know for sure I've never seen one of these here in the States, so once again, thank you for the education.
