Maeuntang as a dish form is pan-Korean; domi maeuntang as a premium expression is most associated with the coastal Gyeongsang region where red sea bream (참돔) is fished
Domi maeuntang (도미 매운탕) uses the whole red sea bream (Pagrus major, 참돔) — one of Korea's most prized fish — in a boldly spiced broth with gochugaru, gochujang, doenjang, garlic, and a backbone of anchovy-kelp stock. The Gyeongsang-do style of maeuntang is the most intensely flavoured regional version: more gochugaru, more garlic, and the addition of doenjang to the broth base alongside gochujang, which the Seoul version typically omits. Whole fish is used rather than fillets — the head, collar, and spine contribute the most flavour and gelatin to the broth; eating the cheek meat (볼살, bol-sal) from a whole domi is considered the reward for the patient diner.
Domi maeuntang's cheek meat (볼살), plucked from the cooked whole fish head, is one of Korean seafood cuisine's most prized single bites — sweet, fatty, and intensely flavoured from the cheek's natural fat content. The broth, drunk from a spoon or bowl, concentrates all the marine and fermented elements into a single complex liquid.
{"Use the entire fish: head and collar contribute gelatin and depth; never remove these before cooking maeuntang","Broth sequence: anchovy-kelp stock first → add doenjang dissolved in small amount of stock → add gochugaru and gochujang → add vegetables (zucchini, tofu, mushrooms) → add fish last","Fish goes in last and cooks only 8–10 minutes — over-cooked sea bream in maeuntang becomes dry and flakes off the bone unappealingly; the flesh should just release from the backbone","Gyeongsang style addition: perilla seeds (들깨, deulkkae) ground and added to the broth in the last 2 minutes — they add creaminess and temper the heat intensity"}
The Gyeongsang-do practice of adding perilla seed powder (들깨가루, deulkkae garu) to the maeuntang broth is a regional distinction that significantly alters the dish's character — it adds a nutty, creamy dimension that rounds the aggressive heat and makes the broth richer. This technique is less common in Seoul-style maeuntang but is the defining element of coastal Gyeongsang maeuntang.
{"Adding fish to cold broth and bringing to boil together — the gradual heat produces a mushy texture; fish should go into already-simmering broth for the proper firm-yet-tender result","Using frozen sea bream — the freeze-thaw cycle breaks the flesh's structure; fresh whole fish is non-negotiable for maeuntang quality"}
