Stew. I hated it as a kid, there were numerous things about the texture that really aggravated my sensory issues, and while my father is a decent cook, I've just never really liked his food very much. We have very different taste profiles. Unfortunately, for many years my parents were financially stressed, so it was a regular occurrence for a single batch of stew to be the entire family's meal for the week. Being the selfish autist that I am, I made my parents' lives hell for that and I sincerely regret this now that I'm adult. I realised many years ago that being able to eat every day, and a balanced meal at that, is actually a massive privilege.
Still utterly refuse to eat anyone's stew made with any recipe, ever. It's poverty food, and it sends me right back to when I was a kid, trying to choke down food that made my scrambled brain scream, "It's poison, get it out of your mouth!"
Two extra things that also affected both my sibling and I is my father's violent hatred of mango and coconut. I found I actually liked fresh coconut, and my father bitching about the smell is a bonus. It took me many years to like mango, however, and even now I can only eat mango if it's in something. I cannot eat a fresh mango. My sibling's spouse has said how strange it was that she had to teach my sibling to like mango, because he'd picked up my father's aversion to it and had carried it for all of his life. For the record, I suspect that my father is actually mildly allergic to mango. The coconut thing is personal taste.
I tried to eat a persimmon once. My mouth went numb, my lips tingled and my tongue started to burn. Two bites in and I threw it away. Maybe it was unripe or something, but I have a voice in the back of my head that tells me, "Yeah, nah, don't eat that shit again."
