So, my girlfriend absolutely loves garlic, but hates onion with a burning passion. I'm reading up on this - they're both allium vegetables, and that's cool and all. But why is she offended by onions, lukewarm on leeks, and greedy for garlic? Chemically, what's going on, here?

I plan to experiment with various kinds of onions to obtain more data.

    I doubt this is a question we can answer (If there is a question here at all). They taste different. She prefers one over the other. Just because they are related botanically doesn't mean she can't have a preference. – moscafj Apr 22 '21 at 20:58
  • Yeah, this is opinion-based and only one person can answer it. – FuzzyChef Apr 23 '21 at 01:01

    In the header and body of this question the love and hate items are swapped. – Willeke Apr 23 '21 at 03:43

    I once cooked for the entire crowd on a villa holiday, with a bunch of friends [in exchange, they did all the other chores]. For two weeks I did this until one friend said, "I love your cooking. Everything my 'ex' made was always full of onions. I hate onions." I told him there had been not inconsiderable quantities of onion in everything I'd made for 2 weeks. He said, "well, yes, but yours are ***appropriate*** onions." Try to work that one out;) – Tetsujin Apr 23 '21 at 18:19

While onions, garlic and leeks are related, their flavours are not the same and a person may well like one but not another, or even like one cooked one way but not another (for example, fried but not raw onion, or roasted but not raw garlic). You ask "chemically, what's going on here" – there are different chemicals, as you can surely intuit by tasting the three for yourself (and each chemical will change during a given cooking process too).

Food preferences are idiosyncratic, and while sometimes you can identify a reason (for example, there is a specific gene related to finding coriander/cilandro unpleasant, or someone might have previously had food poisoning after eating a particular item and afterwards be unable to stomach it) on the whole you shouldn't expect an explanation deeper than 'because she does'.
