The cilantro tasting like soap thing is genetic, but its not necessarily a genetic thing that you are stuck with all your life. It’s a bit more nuanced than that. There have been quite a few studies that have shown where the gene was located, but that it isn’t an exact predictor of cilantro preference. Sometimes its a cultural, and people just get used to it (or at least tolerate it).

Two studies published this week link the aversion for cilantro with specific genes involved in taste and smell. But, just like the flavors of the herb itself, the findings are nuanced: The genes appear to influence our opinion of cilantro but probably not as much as we initially thought.
The authors propose that this odor gene contributes to a person’s dislike for cilantro because it increases the herb’s soapy smell.
But, “it didn’t make a huge a difference in cilantro preference from person to person,” Nicholas Eriksson, the lead author on the study, tells The Salt. In fact, their results suggest that a hatred for cilantro has only a small underlying genetic component. He and his team just published their findings on the arXiv.org.
Overall, Eriksson says these studies demonstrate that DNA does shape our opinion of cilantro, but probably not enough that we can’t overcome it. “It isn’t like your height, that you’re stuck with. People can change it,” he says.
From my own personal anecdote, I used to hate cilantro as a teenager. Couldn’t eat it if it was on the same plate as my food. Sometime in college, I started to tolerate it if it was cooked (like Chipotle’s cilantro rice). Eventually I could tolerate raw cilantro in small dose. By my 30’s, I started to actively put it on appropriate dishes. I even grow it now in my herb garden. I wasn’t actively trying to change my hate of cilantro, it just happened naturally.
Of course your milage may vary. I’m sure most people don’t care enough to overcome it (or the foul taste is so strong most people don’t want to overcome it). For me, it became unavoidable as my tastes naturally went to cuisines that use a lot of cilantro and it didn’t always remember to order w/o cilantro.
