Cilantro only needs 10 minutes with lemon juice, tomatoes, etc to get rid of the soapy molecules. If the leaves are touching hot oils, it also tones down the the soapy molecules. Obviously, assuming the rest of the plate is not massively overpowering the small amount of chopped cilantro at the end.

I've only heard of this soapy cilantro thing on the internet.
I don't actually believe it's real.
