Ham.
I can’t even think about it without having to suppress a gag reflex. I was forced to eat the disgusting, chewy, fatty, greasy slabs of the stuff as a child, throwing up on the dinner table a few times, and carry the extreme taste aversion to this day.
Por in all of its other forms is wonderful, though. Bacon, sausage, loin, roast…yummy. But whatever satan-bile that makes ham taste and smell the way it does is horrid.
Im not a picky eater but …
• mayo
• baked fish
• that grey cooked blood stuff around meatloaf
• eggs in any form - they smell like farts, ppl! cant you smell it???
• liver but who in their right mind likes it anyway?
• and Im sick of Vienna hot dogs after eating 6 of them too. :rolleyes:
This may be the only flavor whose appeal is truly unimaginable to me. I absolutely cannot comprehend how anyone could find it pleasing.
Coffee, wine, and eggs are probably the top three for me that fit the OP. (Squash, zucchini, and their ilk, too, but I’m not sure how popular those actually are.)
My sweet tooth also does not include anything sweet that’s also fruity or tart, or flavored like one of those sweet spices. So, there’s a whole swath of sweets and treats that others seem to really go in for that I’d prefer to just send right down the disposal:
lemon bars
sweet-cheese Danishes
pumpkin pie (or pumpkin anything, actually)
carrot cake
apple-and-cinnamon ___________ (fill in the blank)
raisins
most fruit pies
Ewwww. Just thinking about all that gross sweetness is making really want a bitter beer.
I can enjoy just about any cocktail ever invented but I cannot stomach a Bloody Mary.
Isn’t the cilantro aversion due to some kind of gene that some people have that makes it taste gross? To people who do like it (like me) I don’t think it tastes anything like vomit or however people are describing it.
De gustibus non est disputandum
Sed pugnandum
Mushrooms. A nasty, musky, rotten smell and taste. Hated them since I was a kid. Even now that I’m a middle-aged adult, my mom sometimes says “maybe you’ll like them now.” I continue to politely refuse because the smell is enough to assure me that if I put them in my mouth it’s a near certainty that I will vomit on the table.
Sushi, at least the kind that includes raw fish. This is a psychological thing. about 15 years ago I was eating some raw tuna rolls, and as I was chewing on one my brain kept repeating “you’re eating RAW fish” over and over again. I chewed faster and faster, trying to beat my rising gag reflex; ultimately I barely managed to swallow through the retching. I have not had sushi since.
I hate cream cheese. Thus I loathe stuff like cheesecake and fancy icing on cakes.
I’d like cilantro a lot more if it were used a whole lot less. A tiny bit is good, more is awful. I’ll be glad when it falls off the “cool new herb of the moment” list.
I’m not a fan of super spicy peppers . I can’t say they taste vile, it’s just that I can’t tolerate the heat. I do love horseradish and peppercorn heat, just not jalapeno/habanero type heat. Everything else so far mentioned I love (well, except perhaps for the Durian & insects, neither of which I’ve tasted).
I’m gradually learning to eat bell peppers, but for a long time, something about the flavor and odor felt like a plastic toothpick shoved straight up my psyche, like they’d evolved some chemical for the express purpose of driving me away.
My wife makes a phenomenal eggplant bharta. Every other eggplant dish I’ve tried ranges from mediocre to revolting. I’d say it’s the sliminess of eggplant, but I can eat me some summer squash, so that’s not it. Speaking of slimy, okra, but that’s not so popular.
Oysters? I really want to like them. Hell, my four-year-old likes them. I can’t stand them.
Olives
Coffee
Fresh Tomato Slices - Love it in sauces/salsa/etc.
Cottage Cheese
Canned 'shooms
Teas, sweetened or not
I do love Cilantro.
Actually, I’ll go with ham as a main dish, too. I love it as deli meat. Do not like it as main meal, though.
It’s totally fine to dislike anything, but I used to be in the same boat and if you’re interested in liking tomatoes, here’s what did it for me: get some GOOD tomatoes (the darker varieties are usually better), cut them into medium-to-thick slices, add add a pinch of salt and black pepper, and then eat JUST the tomato with a knife and fork.
I don’t know why, but using flatware made it vastly more palatable and I could appreciate the flavor a lot more.
Peas. Can’t stand the things. Ever since I was a little kid I’ve hated the taste of peas. If I’m in a situation where I feel like I have to have them (say being a polite guest for dinner) I’ll swallow them whole with a sip of water.
Love homemade pea & ham soup though. 
Maybe the drying process makes them more palatable or the smokey bacony flavor of the ham wins out.
I like some kinds of seafood - but I would never order it as a meal if there are other choices. One exception is fish & ships. Batter or crumb it and fry the hell out of it and I’m good.
Raw oysters - no. Just no. Tried them a few times, like chunks of sea-water flavoured phlegm. Some parts of Australia coughing up a big chunk of phlegm when you have a cold is referred to as a “Bush oyster” which is completley appropriate (other parts of the country a bush oyster refers to a bull’s testicle when cooked and eaten). Either way, both should be declined if they are offered to you to eat. 
Onions - which sucks, because so many dishes use them.
Salad of any kind.
Pickled anything.
Hard-boiled eggs (or any other kind of food that reeks.)
Melon of any kind.
Coffee
Tea
I grew up in a Catholic family where the only exposure to fish was fish sticks on Fridays during Lent, and the occasional fried shrimp that I’d share with my brother at a restaurant. I wouldn’t say I hate fish, but I’m fish ignorant. Wouldn’t know what to try, and it’s so expensive at restaurants that I’d rather just order what I know I like.
Onions. Ick. I hate that crunchy texture, even when they’re cooked. Mom used to chop them up in tiny bits thinking I wouldn’t know they were in there. I knew. I’d rather she left them in BIG bits so I could pick them out. Don’t mind the taste, sometimes even add onion powder to dishes. Just don’t want to bite into them. Ick.
Cilantro. I can handle it in very small doses. When food is garnished with cilantro, as many Indian restaurant dishes are, I ask for it without. I will never add it.
Most vegetables in general. I’m a meat-and-potatoes kind of gal. And unfortunately, it shows. Corn is okay, jalapenos, avocado (yeah, I know technically it’s a fruit), and that’s about it. Tomatoes are an ingredient in things like pizza, spaghetti sauce, soup, and ketchup. They are not eaten solo. 
I like cake. I like ice cream. I do not understand why they have to be served together for special occasions. Mixing them just ruins both. 
…and people think I’M the freak when both are being served and I ask for one without the other.
Beer
Mayonnaise
Tuna
Peas
Bananas
For the latter three, just the smell is enough to make me retch, never mind the taste.
Spaghetti and lasagna.
Peanut butter.
Bananas. I can barely even stand to touch or smell a peeled banana. Hate them.
Raisins. I’m a pretty picky eater but can force down most stuff if I absolutely have to. Not raisins.
Yogurt.
Alcohol.
Almost every breakfast food except pancakes and bagels.
I also have almost no sweet tooth. I like chocolate chip cookies, brownies, and chocolate sprinkle donuts and that’s about it. The rest of the desserts I’ve encountered range from “could eat it but will usually skip without a second thought” to “gross.”
Oh yeah I forgot I hate these too. Except the beer. Me likey beer!
I’m another tomato-hater. I love all kinds of tomato sauces and ketchup, and don’t mind tomato chunks in things, but I know people who can sit down with three giant tomatoes, a knife, and some salt and eat them all. I can’t understand that.
A certain percentage of the population actually has a gene that causes cilantro to taste like soap, so that explains why it’s a common food in this thread.
Cooked carrots are another food I don’t like. Raw carrots? One of my favorite vegetables. When you cook them, they just get mushy and weirdly sweet.
