  3. 3Simmered in plain water, anchovy stock or pork-bone broth
  4. 4Sour and savory rather than heavily fatty or thickened
  5. 5An everyday rice-accompaniment soup, not a banquet centerpiece

Substitutions

  • Pork-bone broth → Anchovy or water brothadmissible

    Lighter but still a proper kimchi-guk

  • Aged sour kimchi → Fresh, unripe kimchiinadmissible

    Breaks the dish — fresh kimchi lacks the sourness that defines the soup's flavor

  • Clear brothy soup → Thick reduced stewinadmissible

    Breaks the dish — reduced thick it becomes kimchi-jjigae, a different dish

Common mistakes

  • Using fresh kimchi instead of sour, aged kimchi
  • Reducing it into a thick stew, blurring it with kimchi-jjigae
  • Over-thickening or over-oiling, losing the light guk character
  • Skipping a proper stock base, leaving it thin and flat
