Just tasted one fruit today. Pretty interesting taste although a bit tart but 3 seeds inside and very few flesh. As a result, not so much to eat from those fruits. It is more a collector specie I reckon.
What color was the fruit?
Yellow? Or orange?
I notice they can be tart if you eat them too early when they are yellow.
When they are fully ripe and orange they taste best.
I'm wondering if you have something besides gardneriana? Or if you don't like tart flavor at all?
The ones I've had are definitely a bit tart, but they are also sweet, and have only one seed per fruit. (At least so far after harvesting 4 fruits)...the seed is not too large, so there is plenty of flesh to eat.
