I bought this labeled as Fwang Tung and I guess I was expecting the curves along the ridges which never came on any of the fruit. The fruit were also longer and more boxy than I expected. The fruit tasted pretty good, sweet, just a bit of acidity. It's balanced and I could continue to eat them, but it did not blow me away, but hey, it's a starfruit and I'm grateful for fresh fruit this time of year!
In any case I was hoping someone could shed some light on what the variety might actually be. Thanks for the help!
