Mine tastes like pineapple and banana. More sweet than P. edulis.
I got to taste one fruit from my vine, I got seeds from gooner 2-3 years ago from his wild collected fruits. And it does taste like pineapple(less banana) or maybe a virgin pinacolada with little drop of acidity so very nice to eat out of hand! no need to add sugar or honey, but my vines are small so maybe later the sweetness will be higher.. Sorry forgot to take a photo..
That's awesome! so exciting to taste something for the first time, especially when you grow it yourself.
I can see the pineapple a little bit. The flavor for me is hard to describe. I just noticed a little banana myself, actually, in one of my vine's fruits this year. Particularly the aroma, more than the taste.
I feel like there's an orange juice (i.e. out of a bottle) taste aspect.
As for fruit quality changing or variation. This has been my experience so far in a few years growing these: the first one or two fruits a vine produces each year are usually not very tasty. After that, the flavor improves during the season. Toward the end of the season the fruit quality can decline a bit too. Drier fruits perhaps but maybe not as sweet.
I also feel like the fruit should drop on its own and if found very soon, is best enjoyed about a day later. Fresh off the ground is good too though. after a couple days, the flavor declines and begins to take on a savory aspect.
Also, there is variation in flavor and sweetness across genotypes, as with most/all fruiting plants. I have grown many of my own seedlings and they do have different characteristics. I had one this year whose fruits were completely sour. Every one. So, that vine was killed-off
Addendum - Fruit size and shape, not surprisingly, are also variable across genotypes. Fruit can be spherical, ovoid, or even pointed at the base. Some of my vines can produce nearly tennis-ball sized fruit and others are like ping-pong balls (though the latter are hybrid vines).
