1st year for a good harvest. I believe this was a Mauritius(updated after puglvr1 mentioned it in post#12) planted some years ago.
I enjoyed some earlier today & decided to pick a few more and eat now... There are probably 30 more on the small tree for later.
These were very sweet & tart combo & so fun to eat with the clear plump juicy flesh surrounded by the egg shell thin shell.
Sorry, didn't have time to stop and take a picture till they were all gone....
