Cilantro is rather one of those "love it or hate it" food items. In general, it leaves a "soapsuds" taste and feeling in my mouth. OTOH, there is a Cilantro crusted snapper they make at Sol Azteca in Boston that is the stuff dreams are made of!
My good friend Ruth Alegria, a noted Mexican chef in the Tri-state area, told me there are TWO kinds of cilantro on the US market. The cilantro with small leaves is the "soapsuds culprit." OTOH, if you make sure to get the large leaves cilantro, that never happens. So far, she seems to be right.
Even so, I use cilantro with a light hand.
Just my $.02
