Coriander Korean Explained Leaves Seeds and Uses

In Korea, coriander is called gosu. A common gene makes many Koreans avoid its soapy taste, but some dishes, like temple food, still use it. This guide covers gosu’s history, science, and role in Korean cooking today. Coriander in Korean is called gosu, from the plant Coriandrum sativum. It belongs to the Apiaceae family. Fresh leaves taste sharp and citrusy. Coriander seeds, called gosussi, taste warm and nutty. Cooks use ground coriander in garam masala and Thai curries.

Ancient Egyptians placed seeds inside Tutankhamun’s tomb. Pliny the Elder, a Roman naturalist, named it from the Greek word koris. The herb traveled from its Mediterranean origin through trade routes to India, China, and Southeast Asia. Korean-grown coriander is usually greenhouse grown, giving it a milder taste and weaker aroma than open field grown cilantro from China.

When Is Gosu in Season in Korea? 

Gosu, Korean for cilantro, isn’t widely grown in Korea. Cilantro prefers cool weather and flourishes in spring and fall, but high summer temperatures make it bolt early. . In North Korea’s Hwanghae Province, gosu appears in kimchi.

This happens during colder months. Dishes like Gosu Musaengchae pair cilantro with daikon radish. This dish is best in winter, when radish is in season. So gosu’s flavor peaks alongside fall and winter harvests. 

Coriander vs. Cilantro Clearing Up the Confusion 

In the US, cilantro means fresh green leaves and stems. Coriander means the dried seeds. Both come from Coriandrum sativum, the same plant behind Korean gosu. Cilantro brings a bright citrusy flavor, often slightly peppery.

Coriander offers a warm earthy flavor with citrus notes. Cooks grind seeds into curry powder, garam masala, and other spice blends. The United Kingdom and Australia call both parts coriander. This naming split confuses home cooks searching Korean recipes that mix cilantro and coriander loosely. 

The Role of Coriander in Traditional Korean Cuisine 

Coriander plays a quiet role in Sachal eumsik, Korea’s temple food. The Jogye Order preserves this Buddhist tradition. Temple cooks avoid oshinchae, five pungent vegetables. Yet gosu kimchi breaks that pattern in Hwanghae Province.

This dish traces back to Kaesong, once part of Gyeonggi Province. Goryeo Dynasty cooking shaped many temple recipes. At Sanchon in Seoul, coriander enhances meat-free dishes. Chefs like Jeong Kwan and Kim Dae-chun honor this heritage. Michelin Guide recognized Bium for this refined philosophy. 

Korean Foods That Pair Well With Coriander 

The Reason Some Koreans Dislike Coriander 

Genetics mostly explains this dislike. Many Koreans carry the OR6A2 gene. This olfactory receptor detects aldehydes strongly. Aldehydes create a soapy taste, similar to soaps and detergents. East Asian ancestry shows higher rates of this trait.

Limited early exposure strengthens the aversion further. Korean cuisine relies on gochujang, doenjang, gochugaru, garlic, ginger, and seaweed instead.To see which flavors dominate the table, explore the most loved Popular Foods in South Korea. These bold flavors rarely include coriander’s sharp aldehyde notes. University of Toronto research calls cilantro uniquely divisive worldwide. 

North Korea vs. South Korea How Cilantro Use Differs 

Hwanghae Province keeps gosu kimchi alive in North Korea. Kaesong once belonged to Gyeonggi Province before 1953. The Korean War shifted this region north. Kaesong once served as the Goryeo Dynasty’s capital. Its refined cuisine still welcomes fresh cilantro today.

South Korea mostly skips cilantro in daily cooking. Buddhist temple cuisine keeps gosu dishes alive there. Sanchon restaurant in Seoul praises gosu with meat-free dishes. This native Korean vocabulary hints at cilantro’s ancient usage. 

The Science of Coriander’s Soap-Like Flavor 

Specific aldehydes cause coriander’s divisive smell. Decanal and dodecanal smell fruity and green. (E)-2-decenal and (E)-2-dodecenal smell soapy and pungent. A genome-wide association study tested 14,604 participants.

Researchers found SNP rs72921001 near OR6A2. This olfactory receptor binds strongly to these aldehydes. Chopping or heating cilantro breaks down these compounds. Lime juice softens the sharp aroma further. Charles Spence, an Oxford gastrophysicist, confirms genetics shapes this reaction.

FAQs

Why Do Many Koreans Dislike the Taste of Cilantro?

A gene called OR6A2 is behind it. It makes some noses extra sensitive to compounds in cilantro, so it smells soapy instead of fresh. That’s why cilantro rarely makes it into everyday Korean cooking. 

Where Is Cilantro Used in Korean Cuisine?

Cilantro is mostly used in two places: Buddhist temple food and gosu kimchi, a dish from the Hwanghae and Kaesong region. It’s rarely used in regular Korean cooking. 

What Are the Best Cilantro Substitutes in Korean Recipes?

For fresh cilantro: use parsley with a little lime juice, or Thai basil.
For dried coriander seeds: use caraway seeds (same amount), cumin (a bit less), or fennel seeds (about half the amount)

Does Cilantro in Korea Taste Different From Cilantro in Other Countries?

Yes. Korean cilantro is usually grown in greenhouses, which gives it a milder taste and weaker smell. Cilantro from places like China is often grown in open fields, so it tastes stronger and more fragrant. 

Final Thoughts

Cilantro and coriander are the same plant, but in Korea, cilantro (gosu) holds a small, unique place. A genetic trait explains why many Koreans skip its soapy taste, yet regions like Kaesong and Buddhist temple kitchens have kept it alive for generations.

Now, Korean-Mexican fusion food and Korean-American cooks are giving it new life. Loved or avoided, gosu still connects old traditions with modern Korean flavors.
