MYSTERY TREE

Angus & I saw this beautiful tree, with immature fruit, as we walked outside
a neighborhood near the park. My friend
had this tree in her yard, which is why
I can identify it. Once, she served the
ripe fruit cut in half, drizzled with honey
& crumbled goat cheese. Delicious.
I once had a sandwich with prosciutto,
Brie cheese, arugula & jam made from this fruit. Also, delicious.

Can you identify this tree?

Here are some hints:
-It is native to the Mediterranean region &
western/Southern Asia.
-It has been cultivated since ancient times;
& is now grown worldwide, including Southern California.
-It prefers full sun in long, hot & sunny Summers; but mild Winters.
-A tree will bear fruit after 2-3 years.
-They grow well in pots, so would be good on a patio.

Can you name this tree?
