So, Fruitguy and Ohiojay, would you say it's fair to describe you both as people to whom it didn't taste like "unbearably awful rotten onions that make you want to gargle for hours to try to get the taste out", just "nothing special / don't really care for it", right?
Not even close. More of a garlicky custard taste.
For me - and apparently boukmn as well - it was as if the fruit was some sort of cruel prank, as if people pretend to enjoy it to get unsuspecting victims to taste it so that their reactions can be secretly filmed for an episode of Punk'd.
I have felt the same way about other fruit, such as Surinam-cherry, Nance, Mabolo and several others. Just like medicines do not work the same on all patients, different fruit "affect" us differently. Some factors include genetics (as you mentioned earlier), stage of ripeness, variety, preparation (if any), and/or climate conditions where the fruit was grown.
(And I don't care what people say, there's no way that freezing something makes something that was fine taste that unimaginably awful. We all know that frozen fruit isn't generally as good as fresh. But it doesn't make things taste like some awful form of concentrated onion rot.)
Have you considered that the frozen fruit may have not been handled properly when shipped halfway across the globe? Perhaps it was left to thaw, and then refrozen? Another possibility is that the fruit was not at the right stage of ripeness prior to being frozen initially, or even that it was treated with a chemical to induce "ripeness" (or treated improperly) and that has affected the end product. There is no way to tell at this point.
