From Wikipedia:
Different people may perceive the taste of coriander leaves differently. Those who enjoy it say it has a refreshing, lemony or lime-like flavor, while those who dislike it have a strong aversion to its taste and smell, likening it to that of soap and bugs.[15][22] Twin studies have shown that 80% of identical twins shared the same preference for the herb, but fraternal twins agreed only about half the time, strongly suggesting a genetic component to the preference. In a genetic survey of nearly 30,000 people, two genetic variants linked to perception of coriander have been found, the most common of which is a gene involved in sensing smells.[23] The gene, OR6A2, lies within a cluster of olfactory-receptor genes, and encodes a receptor that is highly sensitive to aldehyde chemicals. Flavor chemists have found that the coriander aroma is created by a half-dozen or so substances, and most of these are aldehydes. Those who dislike the taste are sensitive to the offending unsaturated aldehydes, while simultaneously may also be unable to detect the aromatic chemicals that others find pleasant.[24] Association between its taste and several other genes, including a bitter-taste receptor, have also been found.[25]
So everyone that doesnt like the taste of cilantro is genetically inferior to those of us who do?
