Kimchi-mari-guksu is a cold noodle bowl of the Korean north, in which thin wheat noodles are drowned in chilled, tangy kimchi brine. The broth is the soured liquid of well-fermented kimchi or watery dongchimi, slackened with cold water and balanced with a little sugar and vinegar until it is sharp, cool, and refreshing. Chopped kimchi, slivered cucumber, and half a boiled egg crown the bowl, sometimes over ice. It is plain home cooking — the everyday way to turn leftover kimchi juice and cold noodles into a bracing summer meal — carried south from the northwestern provinces by war-era refugees and now eaten across Korea.
The dish comes out of the cold-kimchi-broth cooking of the northwest, especially Hwanghae province, where cold rice was long mixed straight into the brine of dongchimi or kimchi for a quick, simple meal — the kimchi-mari, or kimchi-dunking, habit. Swapping noodles for the rice gave the cold-noodle form, and a more refined late-Joseon version set it in pheasant or beef broth. With the upheavals of the Korean War, refugees from the north carried the dish south, where it spread nationwide and was simplified to use ordinary kimchi juice. It is a home-style folk dish rather than any one cook's creation, rooted in the dongchimi country of the north.
The first taste is a cold, sour, slightly fizzy snap of fermented brine, clean and mouth-watering, with a measured sweetness and a salty-spicy edge from the kimchi. The noodles are thin, smooth, and slippery, served properly cold so they slide and stay springy in the icy broth. Crunchy slivers of cucumber and a tangle of chopped kimchi add fresh bite and chew, while the boiled egg gives a soft, mild contrast. It eats light and reviving, sharp enough to wake up a dull appetite on a hot day — sour-cold refreshment in a bowl.
The broth is fermentation made to work as seasoning. As kimchi or dongchimi ripens, lactic-acid bacteria turn its sugars into lactic acid and a little carbon dioxide, building the sour, faintly effervescent, deeply savory brine that becomes the soup base — no cooking required, just dilution and balancing. Cold water tames the acidity, sugar rounds it, and a splash of vinegar sharpens it back up to the desired tang. Serving everything ice-cold matters twice over: it makes the sour broth bracing and clean on the palate, and it keeps the wheat noodles firm, since chilling tightens their gelatinized starch into a springier, more slippery strand than they have warm.
Variations
The broth ranges from pure kimchi brine to clear dongchimi liquid to a blend, and the more old-fashioned northern style sets the noodles in a cold meat or pheasant stock seasoned with kimchi juice. Toppings shift with the cook — cucumber, pear, sesame seeds, and a boiled egg are common, and a scoop of ice is usual in summer. Thin wheat somyeon is standard, though buckwheat or other noodles appear. It is close kin to the kimchi-mari rice bowl it grew from, and a humbler, home-kitchen cousin of the grand cold noodle soups mul-naengmyeon and dongchimi-guksu.

How it's made
7 steps · 20 min active + 5 min waiting
- 15 min
Chill the kimchi brine or dongchimi liquid well; if using kimchi, squeeze the juice from well-fermented kimchi and reserve the leaves.
- 25 min
Dilute the brine with cold water and season to taste with a little sugar, vinegar, and salt until cool, sour, and balanced; keep it cold.
Watch outBalance the diluted brine until it's cold, cleanly sour, and rounded — taste it icy, since chilling mutes both the sour and the sweet, and a flat broth sinks the whole bowl.
- 35 min
Chop the kimchi, sliver the cucumber, and halve a boiled egg for the toppings.
- 44 min
Boil the thin wheat noodles until just done, then drain.
- 53 min
Rinse the noodles thoroughly under cold running water, rubbing off the surface starch until they are clean, cold, and springy.
Watch outRinse the noodles under cold running water, rubbing off the surface starch until they feel clean and squeaky — leftover starch makes them slack and gluey in the cold soup.
- 62 min
Coil the chilled noodles into bowls and pour the cold kimchi broth over them.
- 71 min
Top with the chopped kimchi, cucumber, and egg, add ice if desired, and serve at once.
