What is Kalguksu?

Kalguksu — 'knife noodles' — are hand-rolled, hand-cut wheat noodles boiled straight in their broth, which turns silky from the flour. Anchovy, clam or chicken versions all exist; all are grandmother food, market food, rainy-day food — the soft center of Korean noodle culture.

How to eat it

Season with the scallion-chili dadaegi if provided; the broth starts gentle.
Eat the noodles first while they're bouncy — they soften in the hot broth.
Kimchi matters here: kalguksu houses live and die by their fresh geotjeori kimchi.

Cooking it at home

Knead flour dough, rest it, roll thin and slice into ribbons.
Boil noodles directly in anchovy-kelp broth with zucchini and potato — the starch thickens the soup.
Finish with garlic and scallion.

Good to know

Flour-heavy and filling — the 'light noodle soup' impression is a trap.

Kalguksu + geotjeori kimchi + summer boknal is a classic combination; Namdaemun market's kalguksu alley is the atmospheric way to try it.
