Why does cilantro taste like soap? Cilantro is one of the most polarizing herbs on the planet. For many, it adds a fresh, zesty kick to dishes from tacos to salads. But for others, the taste of cilantro is unpleasantly similar to soap. This stark contrast in how cilantro is perceived has sparked intrigue and curiosity over the years. If you’ve ever wondered why cilantro tastes like soap to some people while others can’t get enough of it, this article will break it down for you. Let’s dive into the science, genetics, and culture behind cilantro’s controversial flavor.
What Is Cilantro?
Before we dive into why cilantro can taste like soap, let’s define what cilantro is. Cilantro (Coriandrum sativum) is an herb commonly used in a variety of culinary dishes. It is most popular in Latin American, Middle Eastern, and Asian cuisines, often used fresh as a garnish or flavoring. While cilantro refers to the leaves of the plant, the seeds are known as coriander, which is used as a spice in many recipes.
Cilantro is known for its bright, citrusy flavor, but not everyone experiences it this way.
The Genetics of Cilantro Taste
Why Does Cilantro Taste Like Soap?
Why does cilantro taste like soap: The perception that cilantro tastes like soap is not a figment of your imagination, and you aren’t alone if you feel this way. It’s estimated that around 4-14% of the population experiences this soapy taste when consuming cilantro. This aversion to cilantro’s flavor comes down to genetics, specifically a gene known as OR6A2.
The OR6A2 Gene
The OR6A2 gene is a member of the olfactory receptor family, which plays a role in how we detect odors. This gene is responsible for recognizing aldehydes, a group of organic compounds found in both cilantro and, you guessed it, soap. People who have a variation in the OR6A2 gene are more sensitive to aldehydes, causing cilantro to taste overwhelmingly soapy to them. Those without this genetic variation may enjoy cilantro’s bright and zesty flavor without any hint of soapiness.
Aldehydes and Their Role
Aldehydes are chemical compounds that contribute to the aroma of many different substances, including herbs and cleaning products. In cilantro, aldehydes such as E-2-decenal and E-2-dodecenal are responsible for its distinctive smell and flavor. These compounds are also found in soap and some insects, like stink bugs, which is why cilantro can taste soapy or even like bugs to some individuals.
Nature vs. Nurture
Interestingly, while the genetic component plays a significant role in how cilantro is perceived, environmental factors can also influence one’s response to it. People who grow up in cultures where cilantro is a staple in the cuisine are more likely to enjoy its flavor, even if they have the genetic predisposition to detect the soapy taste. Exposure to cilantro from a young age can help people acclimate to its flavor and eventually enjoy it.
The Science Behind Taste Perception
How Does Taste Work?
To understand why cilantro tastes like soap to some, it’s helpful to have a basic understanding of how taste works. Our taste buds are sensitive to five basic flavors: sweet, sour, salty, bitter, and umami (savory). However, taste is a complex sense that also involves smell, texture, and even temperature.
Taste receptors in our taste buds send signals to the brain when they detect certain compounds. But this isn’t the whole story—our olfactory receptors in the nose also play a significant role in how we perceive flavor. In the case of cilantro, the olfactory receptors pick up the aldehydes, which some people interpret as soap.
Taste and Smell Connection
Since much of our perception of flavor is linked to smell, it’s easy to see why the aroma of cilantro could lead to a strong aversion. When people say that cilantro tastes like soap, they are often describing a reaction to its smell more than the actual taste. This is why plugging your nose while eating cilantro might reduce the intensity of the soapy flavor for those who dislike it.
Why Cilantro’s Flavor Is So Divisive
Cultural Preferences and Cilantro
Why does cilantro taste like soap: Cilantro’s divisive flavor can also be linked to cultural factors. In cuisines where cilantro is used extensively, such as Mexican, Indian, or Thai cooking, people are more likely to develop a preference for it. The repeated exposure can override the initial aversion, and in many cases, people who once found cilantro unpleasant grow to tolerate or even enjoy it.
In contrast, individuals from cultures where cilantro is less prevalent may find its taste more jarring and unfamiliar, leading to stronger negative reactions.
Evolutionary Background
There is also speculation that our aversion or preference for certain flavors could be tied to evolution. In early human history, bitter and strange flavors were often associated with poisonous plants. This may explain why some people are more sensitive to certain flavors and why cilantro’s flavor can trigger a negative response for some.
Can You Overcome a Cilantro Aversion?
Is It Possible to Train Your Taste Buds?
Why does cilantro taste like soap: The good news is that it is possible to overcome an aversion to cilantro. While genetics do play a significant role, taste buds are not set in stone. With repeated exposure, many people find that they can learn to enjoy cilantro over time.
One technique is to start by using small amounts of cilantro in dishes and gradually increase the quantity as you get used to the flavor. Pairing cilantro with ingredients you already enjoy can also help make it more palatable.
Cilantro Substitutes
If you find cilantro intolerable and don’t want to put in the effort to acclimate your taste buds, there are several substitutes you can use in recipes. Fresh parsley, basil, or mint can provide a similar freshness to your dishes without the soapy aftertaste. Each of these herbs has a unique flavor, so choose the one that best complements the dish you’re preparing.
