What makes this special
- Agwi-tang centers on tender monkfish and daikon simmered into a spicy, oceanic southern coastal broth.
- Daikon simmered 8 minutes before monkfish goes in to build sweet broth
- Medium-heat 10-minute cooking dissolves monkfish collagen into the broth
Key ingredients
Core cooking flow
- 1 Rinse 500 g monkfish briefly under cold water, cut it into serving pieces, and pat it dry well.
- 2 Cut 150 g Korean radish into large chunks so it can sweeten the broth without breaking apart.
- 3 Put the radish into 1.5 L anchovy stock and bring it to a steady boil over medium heat.
Agwi-tang is the soup form of Korea's monkfish repertoire, originating along the fishing villages of the southern coast where the fish - known as agwi or agu depending on dialect - is caught and sold fresh daily. Where braised preparations like agwi-jjim build intensity through reduction and heavy sauce, the tang prioritizes the broth. Anchovy stock is the base; radish simmers in it for eight minutes to release its sweetness before the monkfish enters. As the fish cooks gently over medium heat, its collagen dissolves into the liquid and gives it body. The monkfish flesh itself is mild and gelatinous, a texture unlike most white fish. Bean sprouts go in at the end to contribute crunch against the soft fish. Sliced green onion and a hit of gochugaru cloud the broth red and add spice. In coastal towns this was morning food - hangover soup served steaming at predawn markets to fishermen and dock workers before the day started.

- 1Prep
Rinse 500 g monkfish briefly under cold water, cut it into serving pieces, and pat it dry well.
If the smell is strong, coat it with 1 tablespoon cheongju and let it sit for just 10 minutes.
- 2Heat
Cut 150 g Korean radish into large chunks so it can sweeten the broth without breaking apart.
Slice 1 green onion on the diagonal, then rinse 100 g bean sprouts and drain them before cooking.
- 3Control
Put the radish into 1.5 L anchovy stock and bring it to a steady boil over medium heat.
Once it bubbles, cook for 8 minutes, until the edges look slightly translucent and the broth tastes sweeter.
- 4Control
Add the monkfish and keep the pot at medium heat for about 10 minutes.
Avoid a hard boil because the flesh can break apart; skim foam from the surface and do not stir aggressively.
- 5Control
Stir 1 tablespoon red chili flakes and 1 tablespoon minced garlic into the broth until the color spreads evenly.
Add the bean sprouts and simmer uncovered for 6 to 8 minutes so they stay crisp, not limp.
- 6Finish
Add the sliced green onion and boil for only 1 more minute so it keeps some bite.
Taste the broth, adjust with salt or soup soy sauce if it is flat, then serve the soup hot.

Korean Cod and Radish Soup
Daegu mu-tang is a Korean cod and radish soup in which the radish simmers first in anchovy broth for eight minutes to release its natural sweetness before the fish goes in. Cod fillets are briefly marinated in rice wine to neutralize any fishiness, then cooked gently - stirring must be kept to a minimum to keep the flesh in large, intact pieces. The finished broth is remarkably clear and light because cod carries very little fat, and the sweetness of the radish merges with the fish's mild umami to create a clean, layered depth. Crown daisy added in the final thirty seconds of cooking releases a sharp herbal fragrance that lifts the entire bowl. Many Koreans reach for this soup as a hangover remedy, prizing the cool, clean aftertaste it leaves.
Korean Monkfish Spicy Stew
Agwi tang jjigae is a monkfish-based dish that occupies the middle ground between a clear soup and a more concentrated, heavily seasoned stew. It features a broth that is noticeably cloudier and carries a more intense flavor profile than what is typically found in either of those two distinct categories. The cooking process starts by simmering sliced radish in plain water for about ten minutes to establish a sweet and clear liquid base. After this time has passed, Korean red chili flakes and a small amount of fermented soybean paste are mixed into the pot. The soybean paste serves a specific purpose in this recipe, as it helps to neutralize any fishy smells from the monkfish while adding a foundational fermented taste to the overall broth. The monkfish is prepared over medium heat, which allows its gelatinous flesh to stay together in large, firm pieces rather than separating into flakes. To add both texture and bulk, bean sprouts are stirred into the pot to provide a crunch that balances the soft consistency of the fish. Water dropwort, which is called minari in Korean, is the final ingredient to be added. It is left to wilt in the remaining heat of the pot after the heat is reduced so that its unique herbal fragrance is infused into the liquid. Although the monkfish has a somewhat strange appearance, its flesh is thick and very sturdy, meaning it does not disintegrate even when cooked for a long period. Furthermore, the substantial layer of gelatin found under the skin melts into the soup as it simmers, providing a natural thickness to the broth without the use of any starch. When served with a bowl of hot steamed rice on a cold evening, this dish functions as a complete and satisfying meal.
Korean Mushroom Porridge (Silky Shiitake Sesame Porridge)
Shiitake mushrooms and onion are sauteed in sesame oil to build a deep aromatic base, then simmered with soaked rice and water for 35 minutes until the grains break down into a silky porridge. Despite containing no meat, the natural glutamates in shiitake produce a full-bodied broth, sharpened with a finish of soy sauce and black pepper. Using rehydrated dried shiitake instead of fresh intensifies the woodsy fragrance further, and adding the soaking liquid to the pot deepens the broth even more. A few drops of sesame oil stirred in just before serving leave a nutty note in each spoonful. Mild and settling, it works as a morning meal or as something to eat when the stomach needs rest.
Maeuntang (Spicy White Fish Radish Stew)
Maeuntang is a traditional Korean spicy fish stew centered on white-fleshed fish such as cod or frozen pollock. The fish is salted for ten minutes before cooking, which draws out excess moisture and the compounds responsible for fishiness, resulting in a cleaner-tasting broth. Radish goes into the pot first and simmers until its clean, mild sweetness dissolves into the water, forming the base. Gochujang, gochugaru, soup soy sauce, and minced garlic are then stirred in to build the spiced, savory broth. The fish and tofu are added together and cooked for ten minutes without being turned over. Instead, hot broth is repeatedly ladled over the top surface so the fish cooks evenly without the flesh breaking apart. Zucchini, green onion, and cheongyang chili are added in the final three minutes to preserve their color and slight crunch. A half tablespoon of doenjang stirred in at the end adds a secondary layer of umami that deepens and rounds out the broth considerably.

Korean Seasoned Radish Greens
Mucheong-namul is a Korean banchan made from the leafy stems attached to daikon radish, blanched and dressed with doenjang and perilla oil. Unlike fully dried siraegi, fresh or semi-dried mucheong retains a grassy vitality that carries through to the finished dish. Radish greens emerge as a byproduct of the autumn kimjang harvest, when whole radishes are pulled from the ground, and rural Korean kitchens have long turned these tops into namul or hung them to dry for winter. Fresh mucheong requires at least five minutes of boiling to break down its tough stem fibers so they soften properly. A thorough rinse in cold water follows, washing away the bitter, astringent edge that develops during cooking. Seasoning with doenjang and soup soy sauce layers the fermented paste's earthy depth over the greens' faintly bitter, grassy character, creating a contrast that makes each bite more interesting than either ingredient alone. Perilla oil is preferred over sesame because its lighter, quieter fragrance complements the greens' natural flavor rather than overpowering it. Stirring in ground perilla seeds at the end thickens the dressing and wraps each strand of mucheong in a nutty coating, producing a noticeably deeper-flavored version than mucheong-namul made without them. A hearty, clean-tasting winter banchan tied to the rhythm of the radish harvest.
Korean Soy Pickled Onions
Yangpa jangajji is a soy-pickled onion made by immersing large-cut onion chunks in a boiled brine of soy sauce, vinegar, and sugar. The hot brine tempers the raw onion's sharp, pungent bite on contact, and as the pickle matures in the refrigerator the sweet-salty seasoning penetrates evenly through each piece. Cutting the onion along its fiber rather than against it keeps the texture firm and crisp after pickling, whereas thin cross-cut slices tend to soften quickly in the acidic brine. Sliced cheongyang chili peppers added to the jar gradually release their heat into the liquid, lending a gentle, lingering spiciness that offsets the sweetness and keeps the flavors from becoming one-dimensional. The pickle is ready after one day of refrigeration but improves noticeably at three days or more as the seasoning continues to deepen. It is a staple accompaniment to grilled meats like samgyeopsal, where its acidity and crunch cut through richness and refresh the palate between bites. It also works well over bibimbap or cold noodles. The brine can be brought back to a boil and reused for a second batch of onions, making this an economical pantry item.
Korean Chive Clam Jeon (Garlic Chive and Clam Seafood Pancake)
Buchu-bajirak-jeon is a seafood pancake of garlic chives and clam meat, pan-fried in a batter made with a mix of all-purpose pancake flour and rice flour. The rice flour addition increases the chew and gives the finished jeon a slightly more resilient texture than plain flour batters. Clam meat releases a briny, oceanic liquid as it cooks that seeps into the batter and flavors it throughout, while the chives add a sharp, grassy counterpoint. Minced garlic and diagonally sliced cheongyang chili worked into the batter suppress any fishiness and build a layered fragrance. A generous amount of oil in the pan over medium heat produces edges that crisp and brown like the outside of a fritter. Waiting until the bottom is fully set before flipping prevents the pancake from tearing. Served with soy dipping sauce or a seasoned soy mixture, the clean salinity of the clams comes through clearly.

Korean Spicy Pollock Stew
Dongtae-tang is a Korean spicy fish stew made with frozen pollock (dongtae), radish, tofu, and green onion in a broth seasoned heavily with gochugaru. The first step is simmering radish on its own long enough to release its clean, slightly sweet character into the base -- this foundation determines the clarity and depth of the finished broth. Once the radish has cooked through, gochugaru, soup soy sauce, and minced garlic are added to transform the pale stock into a vivid red, peppery liquid. The pollock is cleaned of scales and fins after thawing, then cut into large pieces so the flesh stays intact through the cooking process. After the fish is added, the stew should not be cooked for more than ten minutes: beyond that point, compounds from the bones leach into the broth, producing a bitter, fishy aftertaste that is difficult to correct. Cheongyang chili peppers add a sharper, more piercing heat than gochugaru alone -- a thin-sliced variety provides brief, concentrated bursts of spice. Tofu goes in during the last five minutes, giving it enough time to absorb the spiced broth without breaking apart. The seasoning the tofu draws in softens and rounds out the intensity of the soup, providing a mild counterpoint to the fish and the heat. The stew carries a bracing, satisfying quality and is especially popular during winter months.
Korean Seafood Hot Pot Soup
Haemul-tang is a Korean seafood hot pot that throws together crab, shrimp, clams, and squid in a fiery, brick-red broth. The liquid starts with gochugaru and plenty of garlic, building a spicy base that the seafood then amplifies with its own briny juices. Radish chunks soften as the pot bubbles, thickening the broth slightly and adding a cool sweetness behind the heat. Green onions and cheongyang peppers go in toward the end for a sharp, vegetal bite. The magic of haemul-tang lies in the convergence of flavors: crab shells release a sweet, crustacean stock; clams open to spill their liquor; shrimp and squid contribute distinct textures from snappy to chewy. The pot is brought to the table still at a rolling boil, and diners pick through the shells and tentacles while the broth continues to concentrate.
Korean Spicy Fish Roe Stew
Altang is a Korean stew built around pollock roe - the egg sacs that are the defining ingredient, distinguishing this dish from the many other spicy Korean seafood stews. The dish originated in east coast fishing towns where fresh roe is available in large quantities during the winter spawning season and must be used quickly. Anchovy-kelp stock simmers first with radish to create a clean, sweet foundation before the roe and tofu are added. Once the roe goes into the broth, something visible happens: the egg sacs release their contents as they cook, turning the liquid cloudy and enriching it with marine oils that give the broth a noticeably heavier, more unctuous body. This transformation is specific to altang and is part of what makes it a different eating experience from other spicy Korean stews. Gochugaru and doenjang season the stew together - the chili bringing direct heat and the fermented paste adding depth - and together they neutralize the fishy edge that pollock roe would otherwise carry. Crown daisy, ssukgat, is added in the final moments. Its sharp, almost medicinal herbal fragrance is the correct counterpoint to the heavy, briny broth. In Korean drinking culture, altang occupies a specific role as a late-night restorative consumed at the end of a long evening. The image of a stone pot of altang arriving at the table still vigorously boiling, at two or three in the morning, is a recognizable part of Korean urban nightlife.
