Alright, folks, gather around the kitchen table because today weāre going to talk about a herb thatās as controversial as pineapple on pizza ā cilantro! Now, I know what youāre thinking, āCilantro? Really? That green leafy thing that tastes like soap?ā Yes, thatās the one! But let me tell you, thereās more to this herb than meets the taste buds.
Cilantro, also known as coriander, is a staple in many cuisines around the world. But itās a bit like Marmite ā you either love it or you hate it. Some people relish its unique flavor, while others claim it tastes like soap or dirt1. And it turns out, this love-hate relationship with cilantro might be written in your genes.
Thatās right, folks, your DNA might be the reason why you think cilantro tastes like a bar of soap. A study found a single-nucleotide polymorphism (SNP) ā thatās a fancy way of saying a variation in a single DNA building block ā thatās associated with the perception of a soapy taste in cilantro1. This SNP is located within a cluster of olfactory receptor genes on chromosome 11, including OR6A2, which has a high binding specificity for several of the aldehydes that give cilantro its characteristic odor.
Now, letās break that down a bit. Olfactory receptors are proteins that bind to odor molecules and send signals to our brain, helping us recognize different smells. The OR6A2 receptor binds to the aldehydes in cilantro, which are compounds that give cilantro its unique smell. So, if you have a certain variant of this receptor, you might be more sensitive to these aldehydes, making cilantro taste like soap.
But wait, thereās more! The study also found that the heritability of cilantro soapy-taste detection is low, about 0.087. That means that while genetics play a role, there are other factors at play too. So, if youāre a cilantro hater, donāt blame it all on your genes. Maybe you just havenāt found the right cilantro dish yet!
So, next time youāre at a dinner party and the topic of cilantro comes up, you can impress your friends with your knowledge of cilantro genetics. And remember, whether you love it or hate it, cilantro is more than just a herb, itās a culinary adventure!
And thatās the end of our cilantro saga, folks. Whether youāre a cilantro lover or a cilantro hater, remember, itās all in good taste!
