칼국수

Kalguksu splits into two Korean words: kal (칼, knife) and guksu (국수, noodles). The name describes the preparation method: after wheat dough is rolled flat, strips are cut directly from the sheet with a kitchen knife rather than extruded through a machine or pulled by hand. References to knife-cut wheat noodles appear in Joseon-era cookbooks from at least the 16th century, making kalguksu among the oldest wheat noodle preparations in Korea.

Wheat cultivation arrived late on the Korean peninsula, where rice and millet dominated. Wheat flour came primarily through trade with China, and early wheat noodle dishes were court foods in the early Joseon period (15th-16th centuries). Kalguksu became a commoner food during the Japanese colonial period (1910-1945), when agricultural policies encouraged wheat cultivation and industrialization lowered flour prices. The transition from elite to everyday food took roughly one generation and was largely complete by the 1930s.

The broth varies by region. Coastal preparations use clam or anchovy stock; inland versions use chicken or beef. Andong in North Gyeongsang Province developed a particular version: chicken-based clear broth with hand-cut noodles, zucchini, and mushrooms, which Andong claims as a distinct regional dish with its own restaurant culture. Seoul's Myeongdong neighborhood became famous in the 1970s for a dense clam-broth version that remains the standard tourist introduction to kalguksu.

Kalguksu experienced a deliberate revival in the 1990s. Korean food writers, framing artisanal eating as a counterpoint to industrial uniformity, championed hand-cut noodles against the instant ramen that had saturated postwar Korean kitchens. The revival was partly nostalgic and partly accurate: fresh-cut noodles absorb broth differently than dried noodles, and the texture is distinct. The hand-cut noodle has not displaced ramen, but it holds a stable position as the noodle made today, not last year.
