I nearly threw out my first bag of siraegi. Not because it was bad — because the word sounds almost exactly like sseuregi (ì“°ë ˆê¸°), Korean for garbage, and when a coworker at Coupang's Bucheon 2 fresh center handed me a bundle during a sorting shift, I genuinely asked if it had gone bad. She laughed so hard she had to sit down. Years later I still hesitate before saying the word, and it turns out I'm far from the only one.

What Is Siraegi-Namul, Exactly?
Siraegi refers to dried radish greens — leafy tops cut off at harvest, blanched briefly, then air-dried in a shaded, ventilated spot until deep green-brown and leathery. Korea's National Institute of Korean Language notes that both dried radish greens and dried outer napa cabbage leaves technically qualify as siraegi, though everyday use reserves "ugeoji" for cabbage and siraegi for radish greens. Good siraegi has pale, tender stems rather than tough, fibrous ones.
Insider's Insight: What struck me most is that siraegi was never a designed dish — it's a byproduct. Radish tops used to get discarded outright until someone realized drying them created a second ingredient essentially for free out of farm waste, which is exactly why it stays cheap even now, and why a small handful expands dramatically once rehydrated.
Why Does It Sound Like "Garbage"?
Despite how often Koreans joke that siraegi comes from sseuregi (garbage), linguists have found zero evidence for that connection — it's a folk etymology with no documented basis. The more credible theory ties the word to "busiraegi" or "ppositraegi," old terms for withered scraps left drying in a storage shed or field. The resemblance to "garbage" is such reliable comedy material that a Korean sitcom once built a scene around a foreign-born character mistaking a perfectly good batch of siraegi for trash and throwing it away.
The Surprising Cultural Divide Around Siraegi
Been There: This is the detail that genuinely surprised me. Reports on North Korean defectors suggest siraegi carries a starkly different image up north, where siraegi-guk gets dismissed as "food for dogs," to the point that defectors describe real culture shock watching South Koreans treat the same dish as a comfort-food delicacy. Spain shows a similar disconnect from the opposite direction — radish greens there get discarded before the radish is even sold, used at most for stock, so Spanish visitors reportedly react with genuine surprise seeing radish leaves served as an intentional side dish rather than kitchen waste.
That gap between "waste" and "delicacy" is really the whole story of siraegi in one sentence.
How to Make Siraegi-Namul
- Soak dried siraegi in warm water about three hours, or boil 30 minutes then let sit covered a further three hours if short on time.
- Rinse thoroughly, squeeze out excess water, and peel away tough outer skin from thicker stems.
- Cut into bite-sized lengths and season with doenjang (soybean paste), minced garlic, and a splash of perilla oil.
- Pan-fry over medium heat five to seven minutes until seasoning fully coats the greens and the raw doenjang smell mellows.
- Finish with sesame seeds and, for extra richness, a spoon of ground perilla seed powder.
Real Talk: Doenjang here isn't a stylistic choice — siraegi is naturally low in vitamins doenjang lacks, and doenjang supplies what siraegi is missing, making the pairing nutritionally complementary rather than just traditional.
Nutrition and FAQ
Siraegi is rich in carotene, chlorophyll, vitamin B, vitamin C, dietary fiber, calcium, and iron, while staying very low in calories, part of why it shows up so often in diet-conscious Korean cooking. Compared to fresh radish, siraegi delivers more concentrated fiber and calcium per gram, since drying removes water weight while nutrients remain.
Worth Noting: Siraegi shows up well beyond soup and namul — stuffed into dumplings, layered into pork-bone soup (gamjatang), and mixed into rice bowls (siraegi-mubap), unusually versatile for what started as discarded farm scrap.
Is siraegi the same as ugeoji? Not quite — siraegi technically covers both dried radish greens and dried cabbage leaves, but everyday usage reserves ugeoji for cabbage and siraegi for radish greens.
Does the name really come from "garbage"? No — that's a popular folk theory with no linguistic evidence behind it.
How long does dried siraegi keep? Stored in a cool, well-ventilated, dry place, it keeps for many months without refrigeration.
What does siraegi taste like on its own? Mildly earthy and slightly bitter before seasoning, which is exactly why doenjang and perilla oil are used to round it out.
Can I use fresh radish greens instead of dried? Yes, though fresh greens need only blanching, not the long soak dried siraegi requires.
Have you ever mistaken a food's name for something completely unrelated, the way I did with siraegi and garbage?
