got to taste one of these fruits the other day...let me tell you what I think honestly,
the fruit was a bit small, even small for this tree, which seems to produce fruits about 1/3rd larger...
the fruit came from a potted specimen...so generally I'm assuming the size is closer to what's pictured still on the tree, about the size of a chicken egg.
the fruit I tasted had been refrigerated for a few days, about 3 im guessing..and I assume it was a bit past its prime.
but the flavor was slightly sweet, and decent...the most curious feature of this fruit is the texture of the pulp...it's more like lychee than anything else i can think of. Firm, almost crisp, and a bit difficult to clean from the seeds.
It is the best rollinia species I've tasted so far other than R. deliciosa (that's not saying much..the only other rollinia i've tasted is R. slyvatica)...but I still have yet to taste a larger fruit from the tree, and one that is at peak ripeness...so far I would only recommend this one to collectors...but maybe the taste is better than what i've had? The owner of the tree has tasted more of these fruits than me, and seemed to enjoy them.
I will let u know if I get to taste any more of these, and if the flavor improves.
