Mamuang, I’m loving this thread, thank you for starting it.
Like @danzeb, the thing that’s coming to mind for me is papaya. I remember liking dried papaya on the few occasions when I tried it (back when I was a kid), but I tried a ripe one and it was one of my most memorably bad eating experiences. Maybe it had gone off? Maybe it was the variety - I hear there are a lot of them? I do know other people loved it (my grandmother, for one).
Also like danzeb, my wife hates persimmons. I think it’s primarily a texture thing.
Several people have mentioned liking preserved plums, and I agree that plum jam can be absolutely terrific. However, I ate a pickled plum once (did not want to offend Great-Aunt Willetta) and it was, again, something never to be forgotten, and hopefully never to be repeated…
