Incense rarely produces fruit. When it does, it's usually small and hollow. Occasionally there will be several mature seeds in the fruit with pulpy arils.

These do not taste good. If you're looking for edible fruit, Incense is not the way to go. I've no experience with cinnicata, so I can't comment on its fruit.

I have found the flavor of a well ripened Incense to be very good, somewhat like a green apple. Mine produces about 100 fruits each year, but only rarely do they have more than 1-3 seeds. P. cincinnata grows over a wide range, and in some areas the fruit is considered very good, while in others not so good, so the edibility depends on the source.
