It varies on the flavor and it's mixes, and texture all together than just one of it...
Some I don't dislike or like, some very few I like, some I dislike but I can bear with it, and many I dislike that I refuse to eat it.
For example, I like bread, and cheese. But I don't like cheese bread or cheese cake... That includes all kinds of pizza no matter what toppings. There's too many of these to mention.
But here's a very specific ones that I know of so far:
Marsmallows because of it's sweet-bland flavor over an overly chewy and dry-like texture. It reminds me of chewing fat meat than a candy. Not a good feeling for me even one would coat it with chocolate.
Alcoholic drinks tastes like it burns. Even one mixed it with a fruit flavor. It's overwhelming in each I tried to taste so far. Yes, I'm a beginner and I dislike it.
Most fruits overwhelm me (except oranges. ironic right? sometimes bananas), which few bites or sips would do before I stop. Yet I dislike cherries the most regardless of it's form as a fruit, as a candy, as a flavor for anything at all.
Most leafy vegetables flavor are still something I couldn't handle yet. I could eat them as a broth, but never directly or in any other cooking method. The flavor for me is too strong and the texture together want me not to swallow it. But mostly because of the texture.
I don't drink tea. Especially when mixed with milk.
Nor iced tea.
Nor rootbeer. Hell, even rootbeer tastes too strong for me.
I can only bear spicy food in certain type of flavors and textures. Best at anything crispy. But never as a sauce or anything too soft or chewy.
ANYTHING THAT DOESN'T INVOLVED EATING SOMETHING THAT FEELS RAW AND TOO BONY AT THE SAME TIME. Please do not guess which food I'm implying...
Pizza.
Because anything else written above.
