A wholesome, deeply comforting soup crafted from slow-simmered stock, aromatic garden vegetables, and fresh herbs, served with crusty bread.
Simmer the whole loach in water for 10 minutes, then grind them coarsely in a food processor with some of the cooking liquid.
Return the ground loach to the pot with the water, doenjang, cheonggukjang, gochugaru, and garlic.
Simmer 20 minutes over medium-low heat, skimming foam, until the broth is rich and slightly nutty.
Add the mung bean sprouts, cabbage, and ground perilla seeds and simmer 10 minutes more.
Finish with spring onions and serve hot with rice.
