I’m a bit like TXRebel there, in that a cooked carrot is a reprehensible thing. The softer it is, the worse it is. I love a raw carrot, on the other hand.
My culinary bugbears are “most forms of blue cheese” and “pretty much any mushroom, even the plain boring white ones”. If I’m looking at a blobette of blue cheese on a cracker, I’ll turn my nose up at it. If I can see the mushroom, it’s a hard sell.
But I deeply love what each brings to a dish.
I like mushrooms as a flavoring, but don’t like them as a main ingredient.
I like ketchup and sun-dried tomatoes, but hate raw tomatoes.
Onions. I’ll happily have onion rings or a Blooming Onion, probably because there’s something to dip them in.
Otherwise, I can’t stand them and I hate how they’re ubiquitous everywhere
I enjoy fresh coleslaw with a variety of ingredients including just enough mayonnaise to add moisture and fatty goodness. The coleslaw restaurants usually serve is chopped cabbage swimming in goop. Blech.
I guess I’m the weird one then, because I’m the opposite. I love fresh, ripe tomatoes (being very careful here, because I am not talking about the -fresh, ripe tomatoes- you see in stores which are gassed unripe greens) from my MiL’s garden in almost all forms. Sliced on tops of salads, mixed with fresh mozz and a bit of vinegar, or with a touch of salt and pepper on a cream cheesed bagel. I even enjoy marinating them and then dehydrating them for out of hand snacking.
Cook it into a sauce, especially a marinara style? Blech, keep it away from me.
I don’t think that I have ever tried buttermilk cookies.
Personally, I love high quality olive oil, but I can not stand actual olives.
I find the shrimp that they serve at Japanese hibachi restaurants pretty good. There’s really not much of a taste at all, and I like the texture. After having it enough at those places I ordered a shrimp appetizer somewhere else, and I found it disgusting, tasting too much of the sea. Something about how the shrimp are prepared in hibachi places makes that taste go away.
I never thought about it before but yeah, porridge is disgusting but a flapjack can be a fine thing.
Another: I would never dream of touching liver. Liver pate, on the other hand…(full disclosure - no longer allowed for medical reasons, but yes, I used to love it.)

Eggs. Love them scrambled or fried. Hard boiled are the devil’s spawn.
As far as eggs go, they are divine in deviled eggs and quiche, and horrible in custards. I also don’t care for them on top of my pizza (here’s looking at you, Australia)
And omelets with the right ingredients are great, but not so if they are smothered in canned salsa. One of my favorite egg dishes is my morning taco. Scrambled eggs with olive muffuletta in hot fluffy wheat tortillas - Really good!
I don’t mind carrots in carrot cake or in beef stew, but I won’t eat carrot sticks, or eat them in any other way by themselves. Or in meatloaf, or anything.
I love sweet potato pie but hate sweet potatoes. Probably because sweet potato pie tastes exactly like pumpkin pie to me.
Quite common actually. I remember a story where in exchange for your soul or something equally important you could live in a world where everything was perfect. Among other things listed in the sales brochure was that it would never rain if you had something planned, automobiles that never broke down, and coffee that tastes like it smells. The hero found out, of course, things were not exactly as represented.
And as far as the second half of your post, yeah, they don’t taste much like even a good cup of joe. I remember at work people at work saying, “Boy do I love coffee,” as they dump an equal weight of creamer and sugar into the cup. No you don’t, really. (see: Starbucks)
For me, spinach. I like the leaves raw but anything past wilted (as in a salad) is green slime to me.
Beets. As a general matter, I find them revolting. (A friend told me, “that’s because you’ve only had canned beets. Try fresh beets roasted in the oven - they’ll change your mind!” I tried. My mind was not changed.)
But pickled beet eggs are exquisite. Okay, I’m not actually eating the beet itself, just a beet-flavored thing - but the beet taste is wonderful.
Eggs. They don’t bother me as an ingredient in baked goods, as a binder for meatloaf and maybe in mayonnaise but I won’t touch them in any other form.
I love playing fetch with Teddy, but I ain’t ever gonna eat him.
Chocolate chip mint ice cream. Universally adored, I hate it. Tastes like mouthwash filled with hard bits of gravel. Welcome to it.
Peas. I like fresh raw peas, and love pea soup, but absolutely detest them cooked. To the point that I’ll pick them out of fried rice that has them in it.
Same thing with raisins. Love them by themselves, but cooked into anything (rice pudding, cookies, raisin bread), I’ll pick them out.
And agreed on the chocolate mint combo. Love chocolate, love mints, hate the combination.
My son is the same way, and I honestly thought he was the only one one the planet who could possibly feel that way. 
I think so too.
Exactly.
I guess I should have specified buttermilk donuts. Those are great.
