I’ll never forget the look on my friend Min-jun’s face. We were at a new Korean-Mexican fusion spot in Los Angeles, and the server had just brought out a vibrant bowl of kimchi tacos, generously garnished with what I thought was the perfect flourish: fresh cilantro. Min-jun, usually so adventurous with food, recoiled as if he’d seen a ghost. “Oh my goodness, what is that awful smell?” he exclaimed, his nose crinkling in pure disgust. He spent the next five minutes meticulously picking every green fleck off his taco, muttering about how it tasted like “soap” and “dirt.” It was a stark reminder of a widely observed phenomenon: a good number of Koreans, much like my friend Min-jun, just don’t cotton to coriander, or cilantro as we call it here in the States. So, why exactly do Koreans often dislike coriander? The core reasons stem from a fascinating interplay of genetic predispositions and deep-seated cultural culinary traditions.
At its heart, the aversion often boils down to a combination of genetic factors that influence taste perception and a historical lack of the herb in traditional Korean cuisine, meaning there’s been little to no cultural impetus to acquire a taste for it. For many, it truly tastes like a mouthful of soap, and that’s not just folks being dramatic; there’s some real science backing that up.
The Genetic Blueprint of Dislike: When Cilantro Tastes Like Soap
One of the most compelling reasons behind the widespread dislike of cilantro among certain populations, including a significant number of Koreans, is genetic. It’s not just a matter of preference or simply “not liking the taste”; for these individuals, cilantro quite literally tastes like soap, dirt, or even crushed bugs. This isn’t some quirky psychological aversion; it’s rooted in our DNA.
The OR6A2 Gene and Aldehyde Perception
Scientific research has identified a specific genetic variant that plays a crucial role in this phenomenon. Studies, including those published in prestigious journals like *Nature*, have pointed to the olfactory receptor gene OR6A2. This particular gene is responsible for detecting a group of chemical compounds called aldehydes. Aldehydes are naturally present in cilantro, and they’re also common byproducts in the creation of soap and detergents. For individuals who possess certain variants of the OR6A2 gene, these aldehydes are perceived much more strongly and unpleasantly.
Think about it: when you taste something, your brain combines signals from your taste buds (sweet, sour, salty, bitter, umami) with signals from your olfactory receptors (smell). If your OR6A2 gene is highly sensitive to the aldehydes in cilantro, your brain gets a strong, negative “soapy” or “metallic” smell signal, which then overwhelms any other potential pleasant notes. It’s not a subtle nuance; it’s a full-on flavor assault that is genuinely off-putting.
While the exact percentage of the Korean population affected by this genetic predisposition isn’t universally agreed upon or precisely mapped, anecdotal evidence and widespread observations strongly suggest that it’s a significant factor. Globally, it’s estimated that anywhere from 4% to 14% of people experience this “soap” taste, with varying prevalence across different ethnic groups. East Asian populations, alongside some Caucasian and African groups, tend to show higher rates of cilantro aversion compared to populations in regions like South America or South Asia, where cilantro is a culinary staple.
So, when a Korean friend tells you cilantro tastes like soap, they’re not exaggerating for dramatic effect. Their genetic makeup is literally telling their brain that they’re consuming something that belongs in the laundry room, not on their dinner plate. It makes perfect sense why they would want to steer clear of it!
A Culinary Canvas Without Coriander: Cultural and Historical Absence
Beyond genetics, the other major piece of the puzzle explaining why Koreans often dislike coriander lies in its complete historical absence from traditional Korean cuisine. Food preferences, after all, are deeply shaped by culture, upbringing, and repeated exposure. If something isn’t part of your culinary landscape, it’s much harder to develop a liking for it, especially if there’s already a genetic predisposition against it.
The Traditional Korean Palate: Robust, Pungent, and Umami
Korean cuisine is renowned for its bold, complex flavors. Staples like kimchi, gochujang (fermented chili paste), ganjang (soy sauce), doenjang (fermented soybean paste), garlic, ginger, and sesame oil form the backbone of countless dishes. These ingredients contribute to a flavor profile that is often:
- Pungent: Thanks to ample use of garlic, green onions, and ginger.
- Spicy: Dominated by the heat of gochugaru (chili flakes) and gochujang.
- Umami-rich: Derived from fermented ingredients, mushrooms, and seafood.
- Savory: Often incorporating meat broths and various seasonings.
In this robust flavor symphony, coriander, with its bright, somewhat citrusy, and for many, soapy notes, simply doesn’t have a traditional place. It’s not just that it wasn’t used; its flavor profile genuinely clashes with many of the established tastes and aromas that define Korean food. Imagine trying to add cilantro to a perfectly balanced bowl of sundubu jjigae (soft tofu stew) or a plate of bulgogi. For many, it would feel like a jarring, unwelcome intruder, disrupting the familiar harmony of flavors they know and love.
What Herbs *Are* in Korean Cuisine?
Instead of cilantro, traditional Korean cooking utilizes a distinct set of fresh herbs and aromatics that complement its existing flavor palette. The most prominent include:
- Perilla Leaves (깻잎, *kkaennip*): Often confused by foreigners with mint or basil, perilla leaves have a unique, slightly peppery, anise-like, and refreshing flavor. They’re incredibly popular, used fresh as wraps for grilled meat (ssam), in kimchi, or as a garnish. Their pungent freshness offers a similar role to cilantro in other cuisines but with a distinctly Korean twist.
- Green Onions/Scallions (파, *pa*): Used in almost every dish, either as a garnish, an aromatic base, or a vegetable. They provide a milder, sweeter oniony kick.
- Garlic Chives (부추, *buchu*): Similar to green onions but with a stronger garlicky essence, frequently used in pancakes (*buchujeon*) or banchan (side dishes).
- Mugwort (쑥, *ssuk*): A less common but traditionally significant herb, especially in spring, offering an earthy, slightly bitter, and aromatic flavor, used in soups, rice cakes, and some stir-fries.
These herbs are integral to the Korean culinary identity, and their flavors are deeply ingrained in the Korean palate from childhood. Cilantro, on the other hand, just never made it to the party, so to speak.
The Role of Exposure and Acquired Taste
Taste preferences are often formed through repeated exposure, especially during formative years. If a child grows up eating cilantro in nearly every meal, they’re likely to develop a liking for it, or at least tolerance. This is why it’s so beloved in Mexican, Indian, and Southeast Asian cuisines. Their palates are conditioned to appreciate its unique notes.
In Korea, there’s simply no such conditioning. Children are not exposed to cilantro, so they don’t have the opportunity to acquire a taste for it. When they do encounter it later in life, perhaps in an international dish, it’s often a novel and, for many, an unpleasant experience that immediately triggers a negative reaction, exacerbated by any genetic predispositions they might have.
It’s a powerful testament to how culture shapes our dietary preferences, creating distinct culinary landscapes where one man’s beloved herb is another’s bitter enemy.
Beyond Aversion: Nuance and Evolving Tastes in Modern Korea
While the general sentiment holds true – many Koreans do not like cilantro – it’s important to acknowledge that taste, like culture, is rarely monolithic. There are nuances and evolving trends, particularly in modern, globalized Korea.
The Younger Generation and Global Cuisine
Seoul, and other major Korean cities, are vibrant melting pots of international cuisine. From Vietnamese pho to Thai curries, Mexican tacos, and various fusion dishes, global flavors are increasingly accessible and popular. Many of these dishes traditionally feature cilantro prominently.
Younger Koreans, particularly those who have traveled extensively, lived abroad, or are simply more adventurous eaters, are often more open to trying and even developing a liking for cilantro. They might encounter it in an authentic Vietnamese pho, where its freshness can complement the rich broth, and through repeated exposure, their palate might adapt. Some might even find that they don’t have the “soap gene” and can genuinely enjoy its flavor.
However, even within this more open-minded demographic, the default setting is often caution. Many international restaurants in Korea that serve dishes with cilantro will offer it on the side or ask customers if they want it, acknowledging the widespread local aversion. It’s a testament to how deeply ingrained the preference is, even as culinary horizons broaden.
Adapting Global Dishes for the Korean Palate
It’s also common for international dishes to be adapted for the Korean palate, which sometimes means omitting or significantly reducing cilantro. For instance, a Mexican restaurant in Korea might serve tacos with green onions and perilla leaves instead of cilantro, or only offer cilantro as an optional add-on. This kind of adaptation ensures that the dish appeals to a broader local audience without alienating those with a strong dislike for the herb.
This isn’t unique to cilantro; it’s a common practice in culinary globalization. Just as an Americanized Chinese dish differs from its authentic counterpart, an adapted international dish in Korea reflects local taste preferences. It’s a smart business move, reflecting an understanding of the local market’s ingrained tastes.
The “Freshness” Factor in Korean Cooking
Koreans definitely appreciate freshness in their food. This is evident in the ubiquitous use of fresh vegetables, crisp banchan, and vibrant garnishes like thinly sliced green onions or julienned cucumbers. However, the *type* of freshness they seek is typically different from the bright, pungent, and sometimes perceived as “sharp” freshness of cilantro.
For Koreans, freshness often comes from ingredients like:
- Perilla: With its unique, almost menthol-like zest.
- Garlic and Ginger: Used fresh and often raw for a powerful kick.
- Green Onions: Providing a crisp, mild oniony bite.
- Sprouts: Mung bean sprouts or soybean sprouts add a refreshing crunch.
- Sesame Leaves: Offering a nutty, herbaceous aroma.
These ingredients provide a “fresh” counterpoint to the rich, spicy, and savory elements of Korean cuisine, but in a way that aligns with the traditional palate. Cilantro’s kind of freshness simply doesn’t fit into this established framework for many.
Understanding the Global Divide: It’s Not Just Korea
While we’re focusing on Korea, it’s worth noting that the cilantro divide isn’t exclusive to this particular corner of the world. It’s a fascinating global phenomenon, highlighting how diverse human taste perception can be.
Where Cilantro is King
In many parts of the world, cilantro is not just liked; it’s practically revered. Think about:
- Mexican Cuisine: Essential for salsas, tacos, guacamole, and stews.
- Indian Cuisine: A ubiquitous garnish for curries, dals, and chutneys.
- Southeast Asian Cuisine (e.g., Thai, Vietnamese): Integral to pho, curries, and fresh spring rolls, providing a distinctive aromatic lift.
- Middle Eastern Cuisine: Used in falafel, tabbouleh, and various meat dishes.
In these cultures, the genetic variant that causes the soapy taste might be less prevalent, or perhaps, sustained exposure from a young age helps overcome any mild genetic predisposition. For people from these regions, the idea of a dish without cilantro might feel incomplete, bland, or just plain “wrong.”
Other Regions of Aversion
Conversely, beyond East Asia, there are other regions where cilantro is met with skepticism or outright dislike:
- Parts of Europe: While not as universally disliked as in some East Asian countries, cilantro is far less common in many traditional European cuisines compared to parsley, for instance. A significant portion of Europeans also report disliking its taste.
- Some American Palates: Even in the U.S., where cilantro is widely available and popular in certain cuisines, there’s a noticeable segment of the population (often jokingly referred to as the “cilantro-haters”) who share the same “soap” perception.
This global perspective underscores that the Korean aversion to cilantro isn’t an isolated quirk. It’s part of a broader, genetically and culturally influenced spectrum of human taste experiences. It reminds us that our sensory world is incredibly diverse, and what’s delicious to one person can genuinely be repulsive to another.
The Psychology of Food Preferences and Aversions
Beyond the genetic and cultural factors, there’s also a fascinating psychological component to food preferences and aversions. Our relationship with food is complex, shaped by memory, emotion, social context, and even the power of suggestion.
Early Experiences and Conditioning
Our earliest food experiences play a significant role in shaping what we like and dislike. If a child is repeatedly exposed to certain flavors and textures in a positive environment, they’re more likely to develop a fondness for them. Conversely, a single negative experience with a particular food, especially if it leads to feeling unwell, can create a lifelong aversion.
For Koreans, the lack of positive early exposure to cilantro means there’s no foundation for developing a liking. When they do encounter it, often later in life, and if it triggers a genetically programmed “soapy” taste, that initial negative experience can cement a strong aversion. There’s no nostalgic memory of grandma’s cilantro stew to counteract the perceived unpleasantness.
Social Influence and Group Identity
Humans are social creatures, and our food choices are often influenced by those around us. If everyone in your family, your friend group, or your broader community expresses a strong dislike for a particular food, it can be difficult to go against that grain. There might be an unspoken social pressure, or at least a lack of encouragement, to try or enjoy that food.
In Korea, where the aversion to cilantro is so prevalent, it becomes almost a cultural identifier. Bonding over a shared dislike for “the green stuff that tastes like soap” can be a common experience. This collective sentiment reinforces individual aversions, making it harder for someone to individually decide they actually like it, or at least to admit it openly.
It’s not to say that Koreans don’t think for themselves about food, but rather that collective food preferences can become part of a cultural identity. Just as certain food rituals are passed down, so too can shared dislikes. It’s a subtle but powerful force in shaping culinary landscapes.
The Power of Expectation
Our expectations can profoundly influence our perception of taste. If you’re told beforehand that something tastes bad, or if you anticipate an unpleasant flavor, you’re more likely to experience it that way. For Koreans, the reputation of cilantro often precedes it.
Someone might approach a dish with cilantro already primed to dislike it, having heard countless stories from friends and family about its offensive taste. This expectation can heighten their sensitivity to the less desirable aspects of cilantro’s flavor, making it even harder to appreciate any potential pleasant notes.
It’s a complex web of biology, history, and social dynamics that converge to explain why that innocent little green herb can cause such strong reactions in certain palates.
Frequently Asked Questions About Koreans and Coriander
Given the strong and widespread reaction to cilantro among Koreans, many people have questions. Here are some of the most common ones, with detailed answers to help clarify this fascinating culinary phenomenon.
Is it only Koreans who dislike cilantro?
No, absolutely not. While the dislike for cilantro is notably prevalent among Koreans and other East Asian populations, it is a global phenomenon that affects people from various ethnic backgrounds. Scientific studies, as we discussed, have pinpointed genetic variants (like in the OR6A2 gene) that make cilantro taste like soap, dirt, or even an insect. These genetic predispositions are distributed across different populations worldwide.
For example, a significant percentage of people of European descent also report disliking cilantro. While it might be a lower percentage than in some East Asian groups, it’s far from being an exclusively “Korean thing.” Many parts of Europe, where cilantro isn’t a traditional herb, also see a higher rate of aversion. Even within countries where cilantro is a culinary staple, like India or Mexico, there are individuals who simply cannot stand it. So, while the observation is strong in Korea, it’s part of a broader human experience of diverse taste perception.
Can Koreans ever learn to like cilantro?
For some, yes, it is certainly possible to develop a tolerance or even a liking for cilantro, especially for those whose aversion isn’t solely driven by the strong genetic “soap” perception. Taste can be an acquired preference, and repeated, positive exposure can sometimes change our palates.
Many younger Koreans, for instance, who travel or are more exposed to international cuisines (like Vietnamese pho or Mexican tacos where cilantro is integral), might gradually get used to its flavor. If the genetic component isn’t overwhelmingly strong, repeated exposure can desensitize the palate to its more pungent notes, allowing other aspects of its fresh, citrusy profile to come through. Pairing it with other strong, complementary flavors can also help mask some of the initially off-putting notes. However, for those with a very strong genetic predisposition, the soapy taste might be too intense to ever truly overcome, regardless of how many times they try it. It’s largely individual, but not impossible for everyone.
What are common herbs and aromatics in Korean cuisine if not cilantro?
Korean cuisine boasts a rich array of fresh herbs and aromatics that are central to its unique flavor profile. These ingredients provide freshness, pungency, and depth without the use of cilantro. Some of the most common and beloved include:
- Perilla Leaves (깻잎, *kkaennip*): These are arguably the most iconic Korean herb. They have a distinct, slightly peppery, nutty, and subtly anise-like flavor. Used extensively as wraps for grilled meats (*ssam*), in kimchi, salads, and various side dishes. They offer a refreshing counterpoint similar to how cilantro functions in other cuisines, but with a wholly different taste.
- Green Onions/Scallions (파, *pa*): Ubiquitous in Korean cooking, green onions are used as a garnish for almost everything, an aromatic base for soups and stews, or even as a main vegetable in dishes like *pajeon* (green onion pancake). They provide a mild, sweet onion flavor and a fresh crunch.
- Garlic Chives (부추, *buchu*): With a more pronounced garlicky flavor than green onions, garlic chives are often found in stir-fries, savory pancakes, and various side dishes, adding a pungent kick.
- Garlic (마늘, *maneul*): While not strictly an herb, fresh garlic is used in extraordinarily generous quantities in Korean cooking, often raw or lightly cooked, providing immense flavor and pungency.
- Ginger (생강, *saenggang*): Fresh ginger is used to add warmth, spice, and a fragrant aroma to marinades, soups, and teas.
- Mugwort (쑥, *ssuk*): A seasonal spring herb with an earthy, slightly bitter, and aromatic profile, often used in soups (*ssukguk*), rice cakes (*ssuktteok*), and traditional remedies.
- Wild Sesame Leaves (들깻잎, *deulkkaennip*): Similar to perilla leaves but from a different plant, offering a slightly stronger, more intensely aromatic flavor, often used in stews or seasoned as a banchan.
These ingredients are fundamental to Korean culinary identity and provide the vibrant, fresh notes that characterize many Korean dishes, perfectly fitting the local palate without ever needing cilantro.
Does this dislike extend to other strongly flavored herbs like mint or basil?
Generally, no. The aversion that many Koreans have toward cilantro is quite specific to cilantro itself, largely due to those unique aldehyde compounds and the genetic predisposition. While individual preferences always vary, there isn’t a widespread, culturally ingrained dislike for other strongly flavored herbs like mint or basil in the same way.
Mint, for example, is used in some Korean contexts, particularly in certain traditional desserts or beverages, though it’s not as prevalent as in Middle Eastern or some European cuisines. Basil, especially sweet basil, has gained popularity with the rise of Italian and other Western cuisines in Korea. Many Koreans enjoy pesto, pasta with basil, or even use it in fusion dishes. The flavor profiles of mint and basil are distinctly different from cilantro’s perceived “soapiness” or “bugginess” and do not trigger the same genetic response.
Therefore, it’s important to understand that the dislike of cilantro is quite targeted and doesn’t typically indicate a general aversion to all strong or pungent herbs. It really is about the specific chemical compounds in cilantro and how they are perceived by a significant portion of the population.
Embracing Culinary Diversity
The story of why Koreans often don’t like coriander is a wonderful example of how culture, history, and biology intertwine to shape our individual and collective taste experiences. It’s not just a preference; for many, it’s a sensory reality dictated by their genetic makeup, reinforced by a culinary tradition that never embraced the herb.
So, the next time you’re sharing a meal with a Korean friend and they gingerly pick every last speck of green off their plate, remember it’s not a critique of your cooking or an arbitrary pickiness. It’s likely a deeply rooted response, a testament to the fascinating complexity of human taste, and a reminder to always offer that controversial garnish on the side!
