What Are Korean Perilla Leaves?
For many English-speaking readers, Korean perilla leaves may look like an unfamiliar herb or leafy vegetable. In Korea, however,
kkaennip is one of the most familiar greens on the table. It is used at home, in restaurants, and especially alongside grilled meat and other strongly flavored foods.
One interesting detail is that kkaennip is not actually a sesame leaf, even though it is sometimes translated that way. It comes from the perilla plant, Perilla frutescens, a member of the mint family. The leaves have a distinctive aroma and a slightly peppery, herbal flavor.
So why do Koreans enjoy a leaf with such a distinctive fragrance?
One reason is how well its aroma works with other foods. Fresh perilla leaves are commonly served with grilled pork, beef, and fish. Their fragrance can help balance rich flavors and strong food aromas, which is one reason they work so naturally with meat and seafood. At Korean barbecue restaurants, a perilla leaf can be used as a wrap with grilled meat, rice, sauces, and other side dishes. The fresh leaf adds an aromatic contrast to the richness of the filling.
But kkaennip is much more than a wrapping leaf. It can be eaten fresh, seasoned as
kkaennip namul, or preserved as
kkaennip jangajji. It is also used in soups and stews and can be included in rice dishes and rice rolls such as
gimbap. Another traditional preparation is kkaennip-kimchi, in which perilla leaves themselves are seasoned and fermented as a kimchi-style side dish. Finely sliced perilla leaves can also be used as an aromatic finishing ingredient, adding a distinctive flavor to a variety of dishes.
There is also a nutritional side to this familiar leaf. Perilla leaves provide dietary fiber and minerals such as calcium and potassium. They also contain carotenoids, including beta-carotene and lutein. A review of Perilla frutescens reported about 5.7 grams of fiber, 296 milligrams of calcium, and 421 milligrams of potassium per 100 grams of raw leaves, although the amount people normally eat in one serving is much smaller. These nutrients are best understood as part of the overall nutritional value of a leafy vegetable rather than as evidence of a special health effect.
Perilla also has a long connection with Korean agriculture. A record of cultivating kkaennip appears in
Nongsa Jikseol, an agricultural book compiled in 1429 during the reign of King
Sejong. This provides a glimpse into the long history of perilla cultivation and use in Korea.
For someone tasting perilla for the first time, its distinctive aroma may take some getting used to. Like cilantro, it is a flavor that people may either love or find unfamiliar. For Koreans who grew up eating kkaennip, however, its aroma is simply a familiar part of everyday meals. That familiar leaf can appear beside grilled meat, wrapped around rice, tucked into a rice roll, or served as a small side dish—making kkaennip a particularly recognizable part of Korean food culture.
A Summer Tradition of Perilla Leaves
Summer was the season when fresh perilla leaves seemed to fill the Korean markets. Whenever my mother saw them in abundance, she would bring home a large amount to prepare for our family.
Preparing them was not a quick task. My mother washed the leaves one by one, carefully rinsing each leaf before placing it neatly on top of the others. She repeated the process until the whole stack was clean and ready. Then she prepared a savory seasoning sauce and used it to make kkaennip jangajji, the perilla-leaf side dish we enjoyed throughout the summer.
In our home, kkaennip jangajji was more than just another side dish. Along with kimchi, it was one of the familiar foods that seemed to be on the table again and again. We could take a few seasoned leaves, place them alongside rice, and enjoy them as part of an ordinary family meal.
That memory became more noticeable after I moved to Canada. For a while, fresh perilla leaves were difficult for me to find, and I realized how much I had taken their everyday presence for granted. A food that had once been so common in the summer markets of Korea was suddenly something I had to look for.
Eventually, perilla leaves began appearing more regularly at Korean grocery stores. The packages I found, however, were much smaller than what I remembered from Korean markets, and the price could feel surprisingly high compared with what I was used to.
Even so, there were times when I bought a package simply because I wanted that familiar taste. I would add the leaves to gimbap or wrap them around grilled pork with rice and other ingredients. Those simple meals could bring back a little of the food culture I had grown up with.
I only became more interested in the nutritional side of perilla leaves later in life. As a child, I simply knew them as a delicious side dish that my mother prepared every summer. Looking back now, I realize that I grew up eating many foods that were both familiar and nourishing without thinking much about their nutritional value.
That realization makes me appreciate my mother's cooking in a different way. The carefully washed leaves, the seasoning she prepared, and the jars of perilla leaves waiting on our table were all small parts of everyday family life. At the time, they seemed ordinary. Today, they feel like a meaningful part of the food memories I carry with me.
How to Try Korean Perilla Leaves at Home
If you are curious about Korean perilla leaves but have never tried them before, you do not need to prepare them from scratch. There are several simple ways to experience kkaennip at home or as part of a Korean meal:
1. Try fresh perilla leaves with Korean barbecue: At a Korean grocery store, look for fresh kkaennip or perilla leaves. You can use a leaf as a wrap for grilled pork or beef, adding a little rice and your favorite Korean sauce or side dish. The fresh aroma of the leaf creates a pleasant contrast with the rich flavor of grilled meat.
2. Add them to gimbap: Perilla leaves can also be added to gimbap. Adding one or two fresh leaves to a familiar rice roll is a simple way to experience their distinctive flavor without making them the main ingredient.
3. Make simple kkaennip jeon: A Korean pan-fried dish made with perilla leaves. A simple home version can be made by dipping whole perilla leaves into a light batter made with Korean pancake mix. Coat the leaves with the batter and cook them in a lightly oiled pan until the batter is cooked and lightly golden. This creates a warm and savory way to enjoy perilla, with a softer and milder experience than eating the leaves completely fresh.
4. Try prepared kkaennip jangajji: If you prefer not to cook, Korean grocery stores may also offer kkaennip jangajji, or seasoned and preserved perilla leaves. These prepared side dishes can be enjoyed in small portions with rice and are an easy way to discover another traditional use of perilla without the preparation involved in making them at home.
For a first experience, there is no need to start with a complicated recipe. Trying a fresh leaf with grilled meat, adding it to gimbap, making a simple kkaennip jeon, or tasting prepared kkaennip jangajji can each offer a different introduction to this familiar Korean ingredient.
Perilla leaves may be an everyday food for Koreans, but for someone discovering Korean cuisine for the first time, they can offer a completely new combination of aroma, flavor, and texture. These simple options make it easier to experience perilla leaves and learn how they are used in Korean cooking.
