Cilantro's Soapy Mystery

Ever wondered why cilantro tastes like soap to some? It's not just a fussy preference, but a genuine perceptual difference. This lesson dives into the science behind this culinary conundrum.

Certain genes affect our taste receptors. A variation in the OR6A2 gene, which influences smell sensitivity to aldehyde chemicals, can make cilantro taste soapy to some individuals.

Cilantro contains aldehydes, which are also present in soaps and lotions. These compounds are responsible for the 'soapy' aroma and flavor that some detect.

The dislike for cilantro varies worldwide. Research shows higher aversion in regions like Europe and Africa, and lower in South Asia, where it's a common ingredient.

Interestingly, while cilantro leaves might taste soapy to some, the seeds (coriander) generally do not, even though they come from the same plant.

Exposure plays a role. People can become accustomed to cilantro's flavor over time, indicating that the genetic predisposition isn't an insurmountable dislike.

Scientists are exploring ways to engineer cilantro varieties with fewer aldehydes, potentially making it palatable for everyone, regardless of genetic makeup.

Cilantro seeds were found in Egyptian tombs, indicating its use and value date back over 3,000 years.
