If you read most Korean food blogs, they will tell you that Koreans don’t eat coriander, aka cilantro. They’ll tell you straight to your face that cilantro and Korean cuisine have never crossed paths before.
As the Ask the Korean blog reported a couple of years ago:
“Korea has never grown cilantro, and cilantro is not a part of Korean cuisine. …
But Korean people’s cilantro-hate is nonetheless interesting, because it is a nice reflection of Korea’s insularity.”
