I'd say for everything that's the same, something else is different.
I don't like fish so I never have it around; I do shrimp occasionally, though. I don't really like pork chops that much either, although I do love pulled pork and the occasional rasher of bacon. I don't ever really buy or eat hot dogs either.
I'm so sick of corn I rarely buy it anymore unless I'm making something like shepard's pie. Still don't like squash, can't stand asparagus or cooked spinach.
Here's kind of an odd one: crunchy foods. As a self-diagnosed misophone, I cannot stand physically eating super crunchy foods. Things I absolutely 100% do not eat because of this: hard shell tacos, croutons, most cereals. I also avoid raw carrots and celery, and very rarely do ice cream cones. Nothing like making yourself angry just by eating...oh and I also never ever get popcorn at movie theaters for this reason as well. I also don't eat chips all that often, especially tortilla chips.
I don't really drink soda anymore so that's a rare thing in my fridge. Don't like milk so only buy it for use in recipes, never to drink.
Since I picked up baking as a hobby I rarely if ever buy junk food like cookies, crackers, or anything from the in store bakery. No reason to when I can make something 100x better and to my own tastes.
Mayo will always be disgusting and nothing will convince me otherwise.
Things I have learned to love as an adult:
(Raw) spinach, turns out I just don't like the nasty frozen stuff boiled and turned into mush.
Poblano peppers, so good. I throw them in almost everything these days.
Black beans, we never had them when I was growing up but they are incredibly versatile and so good.
Pink Lady apples.
A lot of baked goods I had never had before are now staples in my household. I am particularly known for my American-style biscotti and all kinds of 'non-traditional' cookies.
Honestly this thread is reminding me of all the things I really want to try and just haven't gotten around to yet.
