Chueo-tang is a southern Korean tonic soup made by blending blanched loach into a smooth puree, straining out bones and skin, then simmering the liquid with doenjang and gochujang for depth. The straining step is what separates a clean, richly flavored broth from a gritty one; every bit of bone and skin must be removed before the long simmer begins. Dried radish greens, siraegi, are added midway and cooked for twenty-five minutes, contributing a fibrous chew that contrasts the velvety broth. Perilla seed powder stirred in near the end thickens the soup to a creamy, pale consistency and layers in a pronounced nutty fragrance that carries through each spoonful. A final pinch of ground sansho pepper leaves a tingling numbness on the tongue that clears any lingering earthiness from the freshwater fish. Loach is high in protein and calcium, and the soup has long been eaten as a summer restorative; a broth that is thick and deeply concentrated is the standard by which a well-made chueo-tang is judged.
Instructions
Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.
- 1Control
Put 600 g cleaned loach into rapidly boiling water and blanch over high heat for 2 to 3 minutes.
When foam and impurities rise, drain the fish in a colander and let it cool completely before blending.
- 2Step
Blend the cooled loach very finely, adding a little of the measured water only as needed so the blades move smoothly.
Press the puree through a fine sieve several times until bones and skin no longer pass through.
- 3Step
Pour the strained loach liquid into a pot and add the remaining measured water to make 1700 ml total.
Whisk in 1.5 tablespoons doenjang, 1 tablespoon gochujang, and 1 tablespoon minced garlic until no large paste lumps remain.
- 4Control
Set the pot over medium heat and stir along the bottom while it comes to a boil.
Once it bubbles, skim the foam, lower to medium-low, and keep stirring occasionally so the blended fish does not scorch.
- 5Control
Add 180 g boiled siraegi and simmer over medium heat for 25 minutes.
Cook gently until the stems soften but still have a chew, and the broth looks thicker and more concentrated rather than watery.
- 6Finish
Stir in 3 tablespoons perilla seed powder little by little and simmer 5 minutes more so it thickens without clumping.
When the soup turns creamy and pale, add 50 g green onion and finish with 0.2 teaspoon ground sansho pepper.

Korean Namdo-Style Loach Soup
Namdo-chueotang is the southern Korean take on loach soup, distinguished from other regional versions by grinding the entire loach - bones and all - into a thick, porridge-like broth. The loaches are first boiled until completely soft, then blended and strained to produce a dense, opaque base packed with protein and calcium. Dried radish greens simmer in this liquid, contributing a rustic, earthy backbone. Doenjang and gochujang season the soup with fermented depth and moderate heat, while a generous addition of perilla seed powder lends a nutty richness that rounds out the heavy flavors. A final dusting of sancho pepper tames any lingering fishiness and adds a tingling, aromatic kick. This is restorative cooking at its most direct - a thick, warming bowl meant to rebuild energy during the colder months.
Korean Gangwon-Style Loach Soup
Gangwon-style chueotang is a thick, hearty loach soup in which the entire fish is boiled, blended smooth, and returned to the pot with ground perilla seeds and dried radish greens. Pulverizing the loach whole dissolves its small bones into the broth, creating a calcium-rich liquid with a distinctive earthy depth. Perilla seed powder transforms the soup into something creamy and nutty, far removed from a typical clear broth. Dried radish greens, rehydrated and chopped, provide a pleasantly chewy counterpoint to the thick liquid. Doenjang and gochugaru add fermented savoriness and gentle heat that deepen the overall flavor. Before blending, the loach should be soaked in salted water to purge any muddy taste, and the perilla powder is best stirred in after the soup reaches a boil so the nutty aroma does not cook off too quickly. The finished soup is dense and substantial, closer to a stew than a broth, and is traditionally eaten in autumn and winter as a stamina food. In the mountainous Gangwon province, chueotang holds a near-legendary status as a warming, restorative meal on the coldest days.
Korean Maesaengi Oyster Porridge
Maesaengi gul juk is a Korean winter restorative porridge made by simmering sesame-oil-toasted rice in anchovy-kelp stock, then finishing it with maesaengi seaweed and fresh oysters. The delicate, threadlike strands of maesaengi lend a mild oceanic fragrance that spreads gently through each spoonful of the porridge. Oysters release briny, mineral-rich juices as they cook, deepening the broth in a way that plain water or a neutral stock cannot replicate. Toasting the raw rice grains in sesame oil before adding any liquid coats each grain with nutty fat, giving the finished porridge a warm, fragrant backbone that ties the seaweed and shellfish together. The anchovy-kelp stock adds its own clean, savory depth that complements both seafood components without overpowering either. Maesaengi must go in at the very last moment before the heat is turned off, because extended cooking destroys its vivid green color and chases away its fresh sea aroma. Oysters should also be added near the end to prevent them from shrinking and toughening. The porridge delivers carbohydrate, protein, and minerals in a single bowl, making it a classic choice for cold mornings or when the body needs gentle nourishment.
Korean Loach Stew (Ground Loach & Perilla Seed Pot)
Finely grinding whole loach into the broth creates the distinctive, porridge-like consistency that defines this traditional Korean stew. Long recognized as a restorative autumn dish, it achieves a heavy body without the use of fatty meats, setting it apart from thinner soybean paste soups. Perilla seed powder introduces a nutty oiliness to the liquid, while dried radish greens contribute an earthy bitterness that grounds the heavy base of fermented soybean and chili pastes. Garlic and green onions establish a savory foundation, and red chili powder supplies a dark color and a layer of sharpness. An alternative preparation involves cooking the fish whole rather than grinding it, which results in a thinner broth where the soft flesh naturally detaches from the bones during the boiling process. This method provides a contrasting texture that is absent in the ground version. Adjusting the ingredients can shift the character of the dish: adding more dried radish greens increases the fibrous texture and bitter edge, while a larger portion of perilla powder emphasizes the nutty qualities. When the stew arrives at the table boiling in a stone pot, the rising steam carries a heavy, concentrated scent that fills the immediate air.

Korean Mushroom Japchae (Shiitake Glass Noodle Stir-Fry)
Beoseot japchae replaces beef with shiitake mushrooms as the primary source of savory depth, making it a staple of Buddhist temple cuisine and vegetarian tables alike. Sweet potato noodles are soaked and boiled, then rinsed in cold water immediately to lock in a firm, springy texture. Shiitake, spinach, carrot, and onion are each cooked separately - their moisture levels and heat tolerances differ enough that combining them prematurely flattens every component. Soy sauce, sugar, minced garlic, and sesame oil bring the noodles and vegetables together, and the finished dish rests for ten minutes so the seasoning penetrates the noodles evenly. The result is a japchae where the mushroom carries genuine umami weight without any meat.
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 Lettuce Root Kimchi
Godeulppaegi kimchi is a seasonal Korean kimchi made from the bitter wild herb godeulppaegi (Korean lettuce root), which is soaked in salted water for about a week to extract most of its sharp bitterness before being dressed in gochugaru, anchovy fish sauce, and glutinous rice paste for fermentation. The extended soak rounds off the bitter edge so that only a pleasant, lingering bitterness remains after fermentation, creating a complex interplay with the lactic acidity. The roots have a chewy, fibrous bite while the leaves turn soft, giving each stalk a dual texture in a single bite. This is a regional autumn kimchi from the Jeolla and parts of Gyeongsang provinces, traditionally prepared in fall to last through winter. The preparation is labor-intensive, requiring patient soaking and careful seasoning, but the resulting depth of flavor is what has kept this variety treasured across generations of Korean home cooking.

Korean Freshwater Crab Spicy Soup
Freshwater crabs are halved, thoroughly cleaned, and simmered in a stock built from radish and doenjang that draws out their intense, briny umami over forty minutes of steady cooking. Gochugaru and cheongyang chili build up layers of fiery heat, while zucchini and radish contribute natural sweetness that tempers the spice. Pressing the soybean paste through a strainer before adding it keeps the broth smooth and clear rather than grainy, and the result is a bold, aromatic stew deeply rooted in Korean regional tradition.
Korean Ginseng Chicken Soup
Samgyetang is Korea's iconic ginseng chicken soup, made by stuffing a small whole chicken with soaked glutinous rice, fresh ginseng, jujubes, and garlic, then simmering it for over an hour. The glutinous rice inside the cavity absorbs the chicken's juices as it cooks, turning into a thick, porridge-like filling that spills into the broth when the bird is broken open at the table. The ginseng lends a subtle bitterness and herbal depth that distinguishes this soup from plain chicken broth, while jujubes contribute a quiet fruity sweetness. The prolonged cooking dissolves collagen from the skin and joints, giving the broth a silky body despite its clear appearance. Seasoning is left to each diner, who dips the meat into salt and pepper on a side plate. Samgyetang is traditionally consumed during the three hottest days of the Korean summer - a practice rooted in the belief that fighting heat with heat restores depleted energy.
Korean Perilla Gamjatang (Nutty Perilla Pork Bone & Potato Stew)
This perilla-forward version of gamjatang places nutty richness at the center of the dish by adding a generous four tablespoons of ground perilla seed to the broth. Pork backbone weighing around 1.2 kilograms is soaked in cold water to draw out the blood, blanched once to clean the surface, then simmered into a heavy, collagen-rich stock that forms the base for everything else. Potatoes and salted napa outer leaves go in partway through cooking, absorbing the deeply savory liquid as they soften. The perilla powder added toward the end turns the broth noticeably pale and creamy, coating it in a smooth, roasted nuttiness that distinguishes this variation from the sharper, more aggressively spiced standard recipe. Twelve perilla leaves are added with the lid on during the final minutes, allowing their herbal fragrance to steep gently into the pot rather than cook off. A spoonful of doenjang strengthens the underlying umami. Gochugaru and gochujang are used to build heat, but the perilla softens and rounds the spice so the overall effect is warmer and less sharp than a conventional gamjatang. Frying leftover rice in the remaining broth at the end is a natural conclusion to the meal.
