Hey Alan,
The fruit look very similar. The leaves seem to deviate just a bit but it could still be the same tree or very closely related.
The fruit that were shared with me this summer from the Haikel tree were so good. Very sweet with alot of flavor. They had some richness to them as well.
My tree produced several fruit but they were too late. Looking forward to picking some of these from my own tree next season.
The flavor seems to be complex and a little hard to describe. Very tastey, sweet, juicey, but not watery. They sometimes reminded me of the flavor of peaches but not every fruit was the same. The flavor also reminds me of another fruit that I just can't yet place. Simply put......they were real good :-).
