i’ve had a similar experience, at first it was incredibly soapy to me. now i genuinely like it and i don’t taste the soap anymore. how could that work though if it’s a genetic trait? could this be stronger in some variants of cilantro? or even on the culantro/cilantro divide?

I'm slightly in this. I love cilantro, but when I heard it tastes like soap to some I just thought "I guess a little bit it does taste that way... but the rest of it tastes better."
