For me it's peas. I hate peas. I can tolerate them in very small amounts or when they're not cooked to mush but I distinctly remember asking my mother, "Must you ruin everything with peas?"

Not a surprise:
raw to partially cooked onions
raw to partially cooked garlic
cilantro
most cheeses

Red Onions. They cannot be simply picked off or ignored, you can still taste them in every bite. Yuck.

I hate chunks of onion in marinara sauce. I'm fine with them in salsa, grilled with peppers for fajitas or cheeseburgers, in chili, and have even gotten to the point where I don't mind raw red onion rings on a salad. But I HATE them in marinara sauce. It doesn't matter whether it's for spaghetti, or lasagna, or pizza, or any other Italian food - it ruins it for me. If I'm served a dish with onions in the marinara, I will put off eating for a few minutes just so I can pick them out - in a subtle way, of course. Used to drive my mother crazy.

Lima beans. They are just gross. Texture and taste yuck yuck yuck.

rosemary. eeeew.

I love broccoli florets, especially with Asian stir-fries! Your hub's loss, your antioxidant/super veggie/tasty gain @dhorst!

Like Cassaendra, I am not a big fan of onions and garlic, and because they have such a strong odor and flavor, even if I pick them out, I still find myself feeling their 'effects' afterward (it's not so much the taste but the effect on me that I don't like). But I have had to eat many veggie dishes with them.

I am pretty used to picking things out, though, being a picky eater. I guess the only thing would be meat. At the Insensitive House, I've been served stuff with meat and told to pick it out, but it just doesn't work that way, given how juices bleed and such.

I also don't like heavy liquors, so a piece of rum or Kahlua cake is not for me, and I can't just eat the icing because the flavor is so strong.

Everything else, I really don't mind eating around. Like I don't like corn or peas, but I just won't eat them if they are in a soup. Whipped cream can be scraped off.

Green Bell Peppers. It's the only thing that I ask to be left out of dishes out to eat, and I will return it if I am ignored. THEY ARE THE WORST.

Saffron, white pepper. Both can ruin an entire meal for me.

Olives. If I'm really hungry and my options are lacking (e.g. the only vegetarian pizza option has olives) I'll pick them out, but I'd rather not. I also pick out capers but they don't render a dish inedible.

Another thing that renders dishes inedible, though I can't say that people love it, are preservatives such sodium benzoate and potassium sorbate. To me they taste and feel like acid burning my tongue. I check ingredient lists. If something such as fruit salad (where it's common) has no such list I avoid it anyway or inquire. Sometimes fruit salad in restaurants comes in big, preserved vats.

Beetroot - there is no picking round it. I agree about melons, too - I once had a misfortune of picking a pineapple chunk out of a fruit salad containing melons, and let's just say, I learnt my lesson.

Chunks of cooked carrots and/or tomatoes. I would eat round them, but usually dishes that contain either are really full of them, so I just give up. Which is why I never eat anything made with chunky tomato sauce.

Chunks of raw yellow onions. And I love onions. But they have to be either sauteed, or caramelised, or pan-fried/roasted, or grilled.

Cilantro – but I can tolerate it in salsa because of all the chili and onion.
Liver – I have that receptor on my tastebuds that makes it taste bitter. That and the mushy texture <shudder!> I'm not keen on giblet gravy for that reason. But liverwurst is a whole 'nother story!
Ketchup – please, bury it decently in a batch of barbecue sauce or keep it to yourself. It's great in barbecue sauce, but ruins a hamburger, to say nothing of French fries.

I think there are a few more, but I can't remember them right now.

hard boiled eggs. they disgust me. i hate the smell, the texture and the taste. i can barely stand to watch someone else eat them. other kinds of egg are okay, though. i think this is the only food i feel so strongly about.

Bananas!

I HATE them and if there are any at all in a fruit salad, dessert, smoothie, or anything like that I spit it out immediately. My friend has a goal of one day making a dessert that has banana in it that I will eat. It's not happening, I loathe anything banana or banana flavored.

Mayo. I hated it when adults who happened to like mayo would tell me to "just scrape it off." It's not something you can "just scrape off." My parents were the worst for that, and then wonder why I wouldn't eat whatever it was. They finally understood when I made dinner one night, and put tons of onions in it. My brother hated onions. He complained, so I told him to "just pick them out." He said the taste of onions was still there. I told him I had to "just scrape off" mayo, and the taste was still there, so he could deal with onions. Mom and dad stopped the "just scrape it off" thing that day.

When I was little, I didn't like onions because of their reputation of making people cry, but now they're just all right.

Most things for me are a matter of good v. nasty preparation (other than meat and fish--I'm a vegetarian). So, for instance, storebought mayo just grosses me out, but I'll happily eat homemade. Undercooked, sproingy eggplant will make me ill, but well-prepared eggplant is delightful. The only kind of food I absolutely cannot tolerate is _bland_ food! Why waste the calories on something that tastes like nothing?

@gourmetgal:

Beets! They taste like dirt to me.

Me too – clean, rich, garden dirt. That's why I love them. Potatoes, too.

Tarragon, watercress and bananas

Eggs. It's an affliction.

I'm so glad to know that I'm not the only ovophobe out there. It's a lonely world.

Anise. It's about the only thing I absolutely cannot tolerate any of whatsoever. Means I'm not too keen on fennel either.

Parsley - no matter how I try to like it, I just can't. It tastes awful to me. I nearly always forget to specific no parsley at restaurants and end up trying to scrape all the little bits off the food or out of the soup.....gag....

For me it's ginger. No gingebread men, gingerbread houses, and I have to be really careful w/ chinese food. I get that one bite and it's over.

I can work around almost anything but melon.

I don't know how much other people love it, but goat cheese repulses me. I wish it didn't. Batali once said that your love of goat cheese depends on whether you knew the barn or the cheese first...and I knew the barn first.

Black olives on pizza or in sandwiches, pastas etc...yuck. BUT I love the cheapie ones right out of the can...go figure.

Cannot stand sour cream; both taste and smell make me gag!! And I can usually taste even a small amount in things. Also, don't like that buttermilk taste. It's ok in baked things cause I don't get that icky flavor.

Not too fond of cream cheese in its natural state or in frostings (it's a texture thing). Don't mind it too much as a carrier in strongly flavored things like blue cheese dip.

Hate, hate, hate liver in all its manifestations.

Anchovies on pizza or salad. What a crime against pizzas and salads.

Green peppers raw. Taste very metallic to me. Used to pick out all the little pieces of pepper and onion in my mom's tomato sauce. Drove my dad nuts. I do like the taste of them cooked, now.

Also, don't like licorice - tastes weird. Can eat small amount of raw anise.

I am a raw celery hater. The taste and stringiness get to me. However, celery is essential to a majority of soups that I make.

Olives! I find nothing takes over the flavor of a dish like those things. They taste like band-aids. Doesn't matter which kind either I am an equal-opportunity olive hater.

Capers, green olives, beets, celery, and anything that tastes like licorice.
