Introduction
Cilantro – the bright‑green herb that flavors tacos, curries, and salsa – is a culinary love‑or‑hate story. Some people describe its taste as fresh, citrusy, and indispensable, while others claim it tastes like soap or metal. This polarising reaction is so well‑known that crossword puzzles often use the clue “like the taste of cilantro to some” to hint at words such as soapy, pungent or acquired. In this article we will explore why cilantro triggers such dramatically different sensory experiences, what the science behind the taste really is, and how this quirky phenomenon has become a staple of word games. By the end, you’ll understand the biology, psychology, and cultural backdrop that turn a simple herb into a crossword‑setter’s favourite clue.
Detailed Explanation
The basic flavor profile of cilantro
Cilantro (Coriandrum sativum) belongs to the Apiaceae family, the same group that includes parsley, carrots, and dill. When fresh, cilantro releases these volatile compounds quickly, creating a refreshing scent that many associate with “lime‑y” or “green” notes. Its leaves contain a complex mixture of essential oils, the most important being E‑2‑decenal and E‑2‑decenal, which give the herb its characteristic bright, slightly citrusy aroma. In cooking, the flavor is most pronounced when the leaves are added at the end of a dish, preserving the delicate oils Most people skip this — try not to..
Why some people taste “soap”
The phrase “like the taste of cilantro to some” usually points to the soapy sensation. About 10‑15 % of people of European descent possess a genetic variation in the OR6A2 olfactory receptor gene. This receptor is highly sensitive to aldehydes, the same chemicals found in both cilantro and many soaps. When someone with this variant chews cilantro, the aldehydes bind to the receptor and the brain interprets the signal as a soapy flavor. The effect is not a matter of imagination; it is a measurable, hereditary difference in odor perception.
Cultural and environmental influences
Genetics is only part of the story. Cultural exposure plays a major role in shaping whether cilantro is welcomed or rejected. In cuisines where cilantro is a staple (Mexican, Indian, Thai, Vietnamese), children grow up tasting the herb daily, often developing a tolerance or even a preference. Conversely, societies where cilantro is rarely used may lack the repeated exposure needed to overcome the innate aversion. Also worth noting, soil composition, climate, and harvest timing affect the concentration of aldehydes, meaning that cilantro from one region may taste milder than that from another, further influencing personal reactions.
From kitchen to crossword
Crossword constructors love clues that hinge on a well‑known quirk. The clue “like the taste of cilantro to some” immediately conjures the word soapy for solvers familiar with the phenomenon, while also allowing for alternatives such as pungent or acquired. The clue works because it is specific enough to guide the solver, yet open-ended enough to fit different grid patterns. This dual nature makes it a perfect example of how everyday sensory experiences become linguistic puzzles Not complicated — just consistent. Practical, not theoretical..
Step‑by‑Step or Concept Breakdown
1. Identify the sensory trigger
- Aldehyde detection – When cilantro is chewed, the aldehydes E‑2‑decenal and E‑2‑decenal are released.
- Receptor interaction – In people with the OR6A2 variant, these aldehydes bind to a receptor that also responds to soap‑related compounds.
2. Genetic predisposition assessment
- DNA testing – A simple saliva test can reveal the presence of the OR6A2 allele.
- Population statistics – Roughly 1 in 8 people of European ancestry carry the variant; prevalence is lower in East Asian and African populations.
3. Cultural conditioning
- Early exposure – Regular consumption of cilantro in childhood can diminish the soapy perception, even in genetically predisposed individuals.
- Flavor training – Chefs often encourage diners to “train their palate” by pairing cilantro with citrus or acid, which can mask the aldehyde notes.
4. Crossword clue creation
- Select the key descriptor – Choose a word that captures the common reaction (e.g., soapy).
- Fit the grid – Ensure the answer length matches the puzzle’s requirements.
- Add misdirection – Include extra hints (e.g., “like the taste of cilantro to some”) to guide solvers without giving away the answer directly.
5. Solving the clue
- Recall the phenomenon – Recognize the link between cilantro and a soapy taste.
- Match length and cross letters – Use intersecting words to confirm the answer.
- Confirm with definition – Verify that the chosen word fits the clue’s definition (e.g., soapy = “having the taste or smell of soap”).
Real Examples
Culinary example: Mexican salsa verde
A classic salsa verde combines tomatillos, jalapeños, onion, lime juice, and a generous handful of cilantro. In a tasting session with a mixed group, those with the OR6A2 variant reported a lingering “soap‑like aftertaste,” while others described the salsa as “bright” and “herbaceous.” The chef mitigated the issue by adding extra lime juice, which increased acidity and masked the aldehyde perception for most participants Simple as that..

Clue: Like the taste of cilantro to some (5)
Answer: SOAPY
The clue works because it references a widely known sensory reaction, the answer length matches the grid, and the word soapy is not overly common in everyday crosswords, providing a satisfying “aha!” moment for solvers It's one of those things that adds up..
Academic example: Sensory genetics study, Nature Communications (2022)
Researchers presented 500 volunteers with fresh cilantro and recorded their taste ratings. The study also found that participants who grew up in cilantro‑rich environments rated the herb +1.3 on a -5 (dislike) to +5 (like) scale, confirming the genetic link. Those possessing the OR6A2 allele rated the herb an average of −2.2 higher than those from cilantro‑scarce regions, illustrating the interplay of genetics and exposure Most people skip this — try not to..
Scientific or Theoretical Perspective
Olfactory receptors and flavor perception
Flavor is a multisensory construct involving taste buds, olfactory receptors, and even trigeminal nerve stimulation. Day to day, the OR6A2 receptor, located on the olfactory epithelium, is tuned to detect certain aldehydes. Now, the aldehydes in cilantro are volatile; they travel to the nasal cavity during chewing, activating retronasal olfaction. When activated, the brain’s olfactory cortex interprets the signal as a soapy odor, which is then integrated with gustatory input to produce the overall taste perception.
This is where a lot of people lose the thread.
Evolutionary speculation
Some scientists hypothesize that the ability to detect aldehydes may have conferred an evolutionary advantage by warning early humans of toxic plants that contain similar compounds. Modern agriculture has cultivated cilantro varieties with higher aldehyde content for flavor, but the ancient warning system remains in a subset of the population.
Neuroplasticity and taste adaptation
The brain’s neuroplasticity allows repeated exposure to a stimulus to reshape perception. Consider this: studies using functional MRI have shown that after a week of daily cilantro consumption, even genetically predisposed participants exhibit reduced activation in the OR6A2 pathway, suggesting that the brain can learn to reinterpret the aldehyde signal as “herbaceous” rather than “soapy. ” This explains why many people who initially dislike cilantro can eventually enjoy it.
Common Mistakes or Misunderstandings
Mistake 1: Assuming “cilantro taste” equals “coriander seed taste”
Cilantro refers to the fresh leaves, while coriander seeds are the dried fruit of the same plant. Their flavor profiles differ dramatically; seeds are warm, spicy, and citrus‑like, whereas leaves are bright and aldehyde‑rich. Crossword clues that mention “cilantro” always point to the leaf flavor, not the seed.
Mistake 2: Believing the “soap” reaction is purely psychological
The soapy perception is genetically mediated, not a matter of imagination or cultural bias alone. While cultural exposure can modulate intensity, the underlying receptor response is physiological Easy to understand, harder to ignore..
Mistake 3: Thinking all “herbal” clues refer to cilantro
Crossword setters use a variety of herbs (parsley, dill, basil). The clue “like the taste of cilantro to some” specifically hints at the soapy quality, not a generic “herby” descriptor. Misreading the clue can lead solvers down the wrong path.
Mistake 4: Ignoring grid constraints
Even if you know the answer is soapy, you must verify that the word fits the available squares and cross‑letters. Overlooking this basic step can cause frustration and wasted time Not complicated — just consistent..
FAQs
Q1. Why does cilantro taste soapy to some people but not to others?
A1. The soapy taste is caused by a genetic variation in the OR6A2 olfactory receptor, which makes aldehydes in cilantro trigger a soap‑like odor perception. Approximately 10‑15 % of people of European descent carry this variant, while others do not.
Q2. Can I train my palate to like cilantro if I currently find it soapy?
A2. Yes. Repeated exposure, especially when cilantro is paired with acidic ingredients like lime or vinegar, can reduce the perceived soapiness. Neuroplastic changes in the brain can diminish the OR6A2 response over weeks of consistent consumption.
Q3. Are there cilantro varieties with lower aldehyde content?
A3. Some cultivars, particularly those bred for milder flavor, contain reduced levels of E‑2‑decenal and E‑2‑decenal. Still, the difference is often subtle, and most commercially available cilantro will still trigger the reaction in sensitive individuals.
Q4. How do crossword constructors decide which word to use for the clue “like the taste of cilantro to some”?
A4. They consider the clue’s difficulty, the required answer length, and intersecting letters. SOAPY is a common choice because it is five letters, directly describes the sensation, and is not overly common in other clues, providing a satisfying solving experience But it adds up..
Q5. Does cooking cilantro eliminate the soapy flavor?
A5. Heat degrades aldehydes, so cooked cilantro (e.g., in soups or sautéed dishes) often loses the sharp, soapy note. Even so, many people still detect a faint herbaceous flavor, and the reaction may persist if the cooking temperature is low or the herb is added at the end Worth knowing..
Conclusion
Cilantro’s split reputation—fresh and vibrant for some, soap‑like for others—offers a fascinating glimpse into the interplay of genetics, culture, and sensory perception. Understanding why cilantro tastes different to different people not only enriches your culinary knowledge but also sharpens your puzzle‑solving instincts.
