Kongip kimchi is a Korean preserved kimchi made by coating individual soybean leaves, one by one, with a seasoning of gochugaru, dark soy sauce, anchovy fish sauce, and plum syrup, then stacking them in layers to ferment. The soybean leaf's earthy, vegetal fragrance is its defining quality in the fresh state, but it transforms into something considerably deeper and more savory once it meets the concentrated umami of soy and fermented fish sauce and begins to mature over several days. Onion and ginger are worked into the seasoning to suppress any raw edge and reinforce the overall aroma. Plum syrup tames the inherent sharpness of the salt and fish sauce with a gentle fruit acidity that rounds the flavor, ensuring that each leaf pulled from the jar tastes balanced rather than overwhelming. The traditional way to eat it is draped over a bowl of warm rice and folded around a mouthful, the salty-spicy leaf acting as both wrap and condiment. When the kimchi is particularly salty after a long fermentation, a brief toss in sesame oil softens the intensity and adds a warm, nutty note. Made in late autumn while the leaves are still young and tender before the first frost, this kimchi keeps for weeks in the refrigerator and deepens in flavor throughout the season.
Instructions
Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.
- 1Season
Rinse 500 g soybean leaves one by one under running water, rubbing both sides gently to remove grit.
Spread them on a draining rack for at least 30 minutes, until the surfaces feel dry enough that seasoning will cling instead of sliding off.
- 2Season
In a bowl, combine 60 g gochugaru, 120 ml soy sauce, 40 ml anchovy fish sauce, 30 g minced garlic, and 8 g minced ginger.
Stir until no dry chili clumps remain and the mixture looks loose, glossy, and evenly seasoned.
- 3Season
Slice 100 g onion very thinly, add it to the seasoning, then stir in 30 ml plum syrup.
Let the mixture sit for 10 minutes so the onion softens slightly and the syrup rounds the salty fish sauce edge.
- 4Season
Gather the drained leaves in stacks of 3 to 4 and spread a thin layer of seasoning on one side of each stack.
Avoid heavy patches, which can make the kimchi too salty, and reach the edges evenly.
- 5Control
Pack the seasoned soybean leaves neatly into an airtight container, pressing them down lightly as you layer.
Fold large leaves in half for easier serving, then spread any remaining seasoning thinly over the top to reduce exposed air.
- 6Season
Refrigerate for at least 1 day so the soy-based seasoning can soak into the leaves.
Before serving, taste one leaf with rice; if it is too salty, toss the portion lightly with a little sesame oil.

Korean Pepper Leaf Kimchi
Gochuip kimchi is a seasonal Korean kimchi made from pepper leaves, prepared during late spring to summer when the leaves are available. Blanching is the essential first step. Fresh pepper leaves contain compounds that produce a raw bitterness, and simply seasoning them without pre-cooking leaves an unpleasant edge. A brief blanch of about 30 seconds collapses the cell structure, removing bitterness while dramatically reducing the volume of the leaves. The softened leaves also accept the seasoning more evenly across their surfaces. Glutinous rice paste added to the gochugaru, anchovy fish sauce, and garlic mixture thickens the coating so it adheres uniformly to each leaf and supports lactic acid fermentation even within the short one-day curing window. The herbaceous quality in pepper leaves survives fermentation, remaining as an undercurrent beneath the spicy coating and producing a green, herb-like character that distinguishes this kimchi from napa cabbage or young radish varieties.
Korean Soy-Marinated Soybean Leaves
Kongnip-jangajji is soybean leaves preserved in a seasoned soy brine - one of the two major leaf jangajji traditions alongside perilla leaf (kkaennip) jangajji. Soybean leaves are larger and thicker than perilla leaves, taking longer to absorb the pickling liquid but offering a more substantial chew, with each leaf large enough to wrap around a spoonful of rice. The brine - soy sauce, water, vinegar, and sugar boiled together - must cool completely before pouring over the leaves; hot liquid softens them into a limp state, destroying the desired texture. Garlic cloves, cheongyang chili, and onion slices added to the jar infuse the brine with aromatic complexity during the curing process, producing a more layered flavor than plain soy. A minimum of two days of refrigerated aging is needed for the seasoning to reach the leaf interior, and flipping the layers once daily ensures even penetration. The most common way to eat it is draped over hot steamed rice, ssam-style.
Korean Steamed Soybean Sprouts
Kongnamul-jjim is a traditional Korean side dish centered on steamed soy bean sprouts. The preparation involves layering fresh bean sprouts with a mixture of red chili flakes, soy sauce, and finely minced garlic before placing them in a pot. A critical aspect of the cooking process is keeping the lid tightly closed from the beginning until the sprouts are fully cooked. This sealed environment creates a build-up of steam that is essential for maintaining the natural crispness of the sprouts while ensuring that the savory and spicy seasoning permeates each individual strand. The resulting flavor profile features a sharp heat from the red pepper that complements the clean and refreshing qualities of the bean sprouts, resulting in a light and clear finish. To finish the dish, a generous drizzle of sesame oil and a handful of sliced scallions are added to provide a fragrant, toasted aroma and a layer of savory depth. Because the primary ingredients are inexpensive and the entire process from preparation to plating takes less than fifteen minutes, this dish serves as a dependable addition to any meal when the table requires an extra side dish on short notice. For a different aromatic profile, perilla oil can be substituted for sesame oil to introduce an earthy and more herbaceous scent. Individuals seeking a more intense level of spice can add sliced Cheongyang chilies during the cooking stage to elevate the heat.
Korean Braised Perilla Leaves
Kkaennip jorim layers fresh perilla leaves with a soy-based sauce and simmers them gently - a banchan built for make-ahead storage. Kkaennip (perilla) is a distinctly Korean herb with an aromatic intensity comparable to basil or mint, yet it is rarely found outside Korean cuisine. The technique stacks five to six leaves at a time, spooning sauce between each layer so every leaf seasons evenly. Simmering on medium-low heat for eight to ten minutes wilts the leaves into soft, pliable sheets that wrap neatly around a mound of rice. The sauce combines soy sauce, gochugaru, sugar, garlic, and sesame oil - the last adding a nutty richness that complements the herb's own perfume. Refrigerated in an airtight container, kkaennip jorim lasts up to two weeks, making it one of the most economical banchan to batch-prepare.

Korean Mapo Tofu Rice Bowl
Soft tofu and ground pork are cooked in a Sichuan-inspired doubanjiang sauce, then ladled over steamed rice. Blanching the tofu in salted water firms it up so the cubes hold their shape through stir-frying. The fermented heat of doubanjiang builds layers of flavor alongside the pork, and a starch slurry thickens everything into a glossy sauce that clings to each grain of rice. A finishing drizzle of sesame oil rounds out the dish, and a pinch of Sichuan pepper adds authentic numbing heat. It can be served as a one-bowl meal, with simple accompaniments chosen to match the sauce, broth, or topping.
Korean Grilled King Oyster Mushrooms
Saesongi-beoseot-gui is a Korean grilled king oyster mushroom dish where the mushrooms are sliced lengthwise to 0.7-centimeter thickness, seared in melted butter until golden on both sides, then glazed with a sauce of soy sauce, minced garlic, oligosaccharide syrup, and black pepper. King oyster mushrooms contain a lot of moisture, so arranging the slices in a single layer without overlap is essential-crowding steams rather than sears, preventing the Maillard browning that gives the surface its golden color and savory depth. Butter burns quickly above medium heat, so temperature control is key, and the soy glaze should only be added after both sides are already browned so it coats the surface rather than making it soggy. Chopped chives and sesame seeds scattered on top add a nutty, aromatic layer over the salty butter-soy base.
Korean White Chili Clam Stew
Baekgochu bajirak jjigae is a clear Korean clam stew where manila clams and daikon radish supply all the broth depth without any additional stock. Starting from cold water is essential: the gradual temperature rise draws the clams open slowly, pulling their briny, mineral-rich juices into the liquid and producing a more fully flavored broth than a quick boil would allow. The clams are purged first in salted water to remove all traces of sand, then placed in the cold pot together with cut daikon. As the water reaches a boil, the clams open and release their liquor into the surrounding liquid; any that remain closed after full boiling are discarded. Seasoning stays measured with minced garlic and guk-ganjang, while diagonally sliced red chili and cheongyang chili add both visual warmth and layered heat to the otherwise clear broth. Scallion is added only at the final moment to preserve its freshness and fragrance. The daikon contributes a cool, gentle sweetness that balances the clams natural salinity and fuses with the shellfish stock to build a broth of surprising complexity. The stew requires no anchovy, no kelp, and no premade stock: clams and radish alone generate the kind of depth that usually takes considerably more effort to achieve.

Korean Pepper Leaf Soy Pickle
Gochuip jangajji is a Korean soy pickle made from pepper leaves, a summer byproduct of chili cultivation, washed and submerged in a boiled brine of soy sauce, vinegar, and sugar. Unlike the chili fruit, pepper leaves carry almost no heat. What they bring instead is a grassy, mildly bitter fragrance that blends naturally with the savory and sour notes of the brine. Boiling the pickling liquid first and letting it cool before pouring it over the leaves preserves some of their texture while ensuring even seasoning throughout. Garlic and cheongyang chili contribute a sharp, pungent edge to the liquid, and the thin leaves absorb the brine fully within a single day. Over time, the pickling liquid penetrates deeper and the umami grows more pronounced. Laying one leaf over rice and folding it into a small parcel combines the roles of banchan and ssam in a single, compact bite.
Korean Perilla Leaf Kimchi
Preparing kkaennip kimchi involves layering a seasoning mixture of soy sauce, Korean red chili flakes, minced garlic, and toasted sesame oil between individual perilla leaves. Unlike traditional cabbage kimchi, this version functions as an instant pickle that requires no fermentation period, making it ready to serve as soon as the assembly is finished. The sharp, herbal aroma of the raw perilla leaf softens when integrated with the toasted richness of sesame oil, while the chili flakes provide a controlled level of heat that complements rather than masks the natural characteristics of the leaves. Soy sauce establishes a savory and salty foundation, which is further elevated by the addition of finely chopped scallions. For a different visual result, using soup soy sauce produces a lighter color that allows the dark green hue of the perilla leaves to remain prominent. Small amounts of anchovy fish sauce can also be added to the marinade to introduce a complex layer of saltiness similar to fermented kimchi. This side dish maintains its quality well in the refrigerator throughout the week. While the seasonings are distinct and bright on the first day, the flavors fully penetrate the leaves after two or three days, resulting in a more integrated profile. The seasoned leaves are commonly draped over warm steamed rice or used as an aromatic alternative to lettuce when wrapping grilled meats. Because it requires few ingredients and minimal preparation time, it is a practical choice for home cooking.
Korean Soy Pickled Perilla Leaves
Kkaennip jangajji is a Korean soy-pickled perilla leaf side dish made by layering thoroughly dried leaves in a brine of boiled soy sauce, rice vinegar, and sugar with garlic and cheongyang chili. One of the most important steps is bringing the brine to a full boil and then allowing it to cool completely before pouring it over the leaves. Hot brine wilts the leaves immediately and collapses their structure, while a cooled brine preserves their shape and allows the seasoning to penetrate evenly over the resting period. The perilla's bold herbal fragrance becomes rounder and less sharp when it comes into contact with the salty depth of the soy sauce, and the vinegar prevents the saltiness from becoming overwhelming, keeping the finish clean and bright. Cheongyang chili leaves a quiet but definite heat at the back of each bite, and garlic threads a pungent undercurrent through the entire flavor profile. Wrapped around a spoonful of plain white rice, a single leaf delivers its full herbal, savory character in one mouthful, and the combination is one of the most satisfying pairings in Korean home cooking. Stored in the refrigerator, the pickled leaves keep for well over a month, making this one of the most practical side dishes to prepare in advance.
