I don’t consider myself to be a very picky eater, so I’m going to have to sit and ponder this question for a minute.
As a kid, I really hated a Norwegian dish called kumla.
Same for German potato pancakes.
(Maybe I just didn’t like the recipe my family used, because these ones from The Spruce look pretty delicious.)
I hate okra too; the slimy insides have always just seemed like snot to me.
Eggplant has never been my thing, although I’d say hate is slightly too strong of a word. I tolerate eggplant.
Oh! I hate American cheese. I think it ruins pretty much anything, including grilled cheese sandwiches. I don’t like the flavor or the texture.
Canned green beans…those definitely qualify as a hate for me. The color is terrible, the flavor is awful, and the texture is a tragedy. I like my green beans to be crisp tender and bright green.
(Boy, I am making a pretty extensive list here for someone who is not a very picky eater. Maybe I am more picky than I think I am!)
Hmm, what else? I don’t like mussels or oysters.
And I wish it wasn’t true, but I hate olives. I have tried really hard to like them because I know how healthy they are, but I just cannot get on board the olive train. Even those fancy marinated ones taste terrible to me.
And that’s all I can come up with right now. I’m sure more items will occur to me later (and maybe some of your hates will remind me of mine!)
