However for some people cilantro tastes and smells like soap. A number of famous chefs abhor(ed) cilantro, including Julia Child, Ina Garten (aka Barefoot Contessa) and Top Chef Fabio Viviani. It turns out that the compound that gives Cilantro the pleasant citrus taste/smell is 2-dodecenal. If you have a mutation in an olafactory receptor, it can't distinguish between 2-dodecenal and 1-dodecenal. 1-dodecenal tastes and smells soapy. So for people who hate cilantro, 2-dodecenal looks and tastes like 1-dodecenal.
