Got some sweet maphuut fruit online.
They were smaller than big maphuut I have seen in some photos and videos, but still good size. Large seeds but nice amount of flesh too, and no visible pest damage on any of the fruit.
Flesh in the middle, around the seeds, tasted (to me) like a bland mayong chit with no sourness at all, but when eating with a spoon near the rind, the feeling and taste reminded of eating a kiwi.
Maybe even better varieties exist, but this one was already a very good package for an uncommon fruit and I feel it could even have commercial potential. Definitely going to plant some of the seeds, and make sure there are several trees within pollination distance.
The supposedly self-fertile air-layered maphuut tree I already have flowered again, and again all the of the few fruit fell off. So it's probably a female tree and doesn't fruit properly by itself.
