Kongguk

Cold Soybean Soup

콩국

A chilled, creamy white soup made by blending soaked and cooked soybeans — served cold over noodles or rice in summer.

Kongguk is Korea's answer to summer heat: a thick, ivory-white liquid made by grinding water-soaked white soybeans until smooth, then straining and serving the result cold, often over thin wheat or buckwheat noodles (in which case it becomes konggukmyeon or kongguksu). The flavour is gently nutty, slightly sweet, and utterly refreshing — a natural dairy-free 'cream soup' that has been part of Korean summer cooking for centuries. Unlike most Korean soups, kongguk is never simmered; the soybeans are simply boiled until soft, then blended raw into the cold liquid, preserving a fresh, clean taste. Seasoning is minimal — just salt at the table — because anything more would overwhelm the delicate soybean character. In traditional Korean medicine, kongguk is celebrated as a cooling, yin-natured food perfect for balancing the body during the humid Korean summer. Grandmothers and health-conscious younger Koreans alike seek out restaurants that grind the soybeans fresh each morning, and the difference in flavour between freshly ground and packaged kongguk is considerable.

✦ Tastypinch tip

If served as kongguksu, use chopsticks to lift noodles and sip the cold soybean broth separately.

How to eat it

  1. Season with a pinch of salt before drinking — unsalted kongguk tastes flat.
  2. Eat during summer months for the cooling, refreshing effect.
  3. If served over noodles, mix noodles into the cold soup before eating.

Common mistakes

  • Adding too much salt — the soybean flavour is subtle and over-salting destroys it.
