Key ingredients
Core cooking flow
- 1 Peel 500 g onion and cut it into large pieces along the natural fibers so the texture stays crisp.

- 3 Combine 180 ml soy sauce, 180 ml vinegar, 180 ml water, and 4 tablespoons sugar in a saucepan.
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.
Instructions
Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.
- 1Prep
Peel 500 g onion and cut it into large pieces along the natural fibers so the texture stays crisp.
If the onion tastes very sharp, soak it in cold water for 10 minutes, then drain it well.
- 2Prep
Slice 2 hot green chilies on a diagonal, keeping loose seeds from scattering too much.
Put the onion and chilies into a sterilized jar, packing them firmly enough to fit but not crushing the onion pieces.
- 3Control
Combine 180 ml soy sauce, 180 ml vinegar, 180 ml water, and 4 tablespoons sugar in a saucepan.
Set it over medium heat and stir until the sugar dissolves before the liquid reaches a full boil.
- 4Control
When the brine begins bubbling across the surface, boil it for about 1 minute only.
Turn off the heat before it reduces heavily, so the vinegar keeps enough acidity and the soy flavor does not become too salty.
- 5Control
Pour the hot brine directly into the jar until the onions are covered.
Press the vegetables down with a clean spoon to release trapped air, then let the jar cool completely at room temperature before refrigerating.
- 6Finish
Refrigerate the jar for at least 1 day, checking that the onion stays submerged.
The flavor becomes more even after 3 days. Serve chilled with grilled meat, bibimbap, or cold noodles, and reboil the brine before reusing it.

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 Soy Pickled Cucumber
Oi jangajji is a Korean soy-pickled cucumber made by slicing cucumbers into one-centimeter rounds, lightly salting them to draw out surface moisture, then packing them into a sterilized jar with whole garlic cloves and green chilies before pouring over a boiling brine of soy sauce, water, vinegar, and sugar. The hot liquid partially cooks the cucumber surface while leaving the center firmly crisp, and two days of cold fermentation allows the sweet, salty, sour brine to penetrate all the way through. The green chilies leave a faint heat at the back of each bite, and the whole garlic cloves release their aroma gradually into the brine as they soften over the resting period, adding a layer of complexity beyond a straightforward soy pickle. Reboiling the spent brine and pouring it back over the cucumbers once extends the crunch considerably, turning this into a practical side dish that holds up well for more than a week in the refrigerator. It works alongside a bowl of rice, next to a hearty soup, or as a sharp palate-waker on a hot summer day when appetite runs low.
Korean Braised Burdock and Konjac
Ueong gonyak jorim is a low-calorie Korean braised side dish of diagonally sliced burdock root and bite-size konjac in soy sauce with oligosaccharide syrup. The burdock is soaked in vinegar water to remove astringency, and the konjac is blanched then dry-toasted briefly to minimize its neutral odor. Adding the syrup once the liquid has reduced by half creates a gentle gloss and softens the salt. Sesame oil and sesame seeds finish the dish with a toasted note. Despite using just a handful of inexpensive ingredients, the contrasting textures of crunchy burdock and bouncy konjac make this banchan more interesting than the short ingredient list suggests.
Korean Soy Pickled Beet (Vinegar Soy Brine Jangajji)
Beet jangajji is a Korean soy-pickled beet prepared by slicing beets thin and submerging them in a cooled brine of soy sauce, vinegar, and sugar. The vinegar cuts through the beet's earthy undertone, leaving a clean sweetness sharpened by acidity, and onion adds a mellow depth to the pickling liquid. As the brine cools, the beet's vivid red pigment bleeds into the liquid, creating a visually striking jar that stands out on the table. After at least a day of pickling, the flavor penetrates fully, producing a crisp, refreshing side dish suited to rice or grilled meats. Julienned beets pickle faster and are ready within a day, while thicker slices need two days or more for the brine to reach the center. Stored in the refrigerator, the pickles keep well for over two weeks, making a large batch practical.

Korean Seasoned Tofu Pouch Sushi (Yubu Chobap)
Yubu chobap fills sweet-savory braised tofu pockets with vinegared sushi rice. The tofu skin absorbs the braising liquid, so each bite releases a light burst of seasoned juice. Finely diced carrot and cucumber mixed into the rice add crunch and color. Sesame oil and whole sesame seeds boost the nuttiness of the rice filling. Each piece is bite-sized and easy to eat by hand, which has made it a long-standing favorite for packed lunches, snacks, and picnic spreads in Korea.
Korean Spicy Glazed Tongue Sole
Seodae-yangnyeom-gui is a Korean spicy-glazed tongue sole dish where cleaned sole is coated with two-thirds of a sauce blending gochujang, soy sauce, Korean chili flakes, plum syrup, sugar, minced garlic, and ginger, marinated for ten minutes, then pan-fried over medium heat for four minutes per side. The flat body shape of tongue sole allows the marinade to adhere evenly across the entire surface, and because the flesh is thin, the salty-sweet seasoning penetrates all the way through quickly. Plum syrup in the sauce contributes a fruit-forward acidity that lifts the heaviness of gochujang, and together with sugar it caramelizes at pan temperature into a glossy brown coating. Brushing the remaining sauce on during the final two minutes builds a double-layered glaze, and finishing with sesame oil and chopped green onion releases a fragrant aroma from the residual heat.
Korean Dried Pollock Napa Stew
This stew pairs dried pollock strips with napa cabbage for a mild, comforting bowl built on clean, unhurried flavors. The pollock releases a savory, slightly sweet depth into the broth as it rehydrates during cooking. Soaking the pollock briefly in water before adding it loosens the stiff fibers and helps the broth extract faster. The cabbage softens slowly and adds its own natural sweetness, while firm tofu and zucchini round out the ingredients with body and texture. A touch of perilla oil lends a nutty fragrance to the finished bowl. Seasoned simply with soup soy sauce, it works well as a hangover remedy or a light weekday meal that settles the stomach.

Korean Pickled Green Onion
Daepa jangajji is a quick Korean pickle made by cutting large green onions into five-centimeter lengths and submerging them in a cooled brine of soy sauce, vinegar, and sugar with garlic and dried chili. Using primarily the white portions yields a firmer, crisper result, and the brine must be cooled thoroughly before pouring to prevent the onions from wilting prematurely. The soy and vinegar together pull back the raw sharpness of the green onion while leaving its aromatic depth intact. Two days of refrigeration allow the seasoning to penetrate evenly throughout each piece. The result is a sharp, savory condiment that cuts through the fat of grilled pork belly or other rich meats, and its simple ingredient list makes it one of the most practical quick-pickles to keep on hand.
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 Pickled Garlic Scapes
Maneuljjong-jangajji is a preserved side dish of garlic scapes pickled in a boiled soy sauce, vinegar, and sugar brine. The preservation principle is identical to that of whole garlic jangajji, but the scape, meaning the flowering stalk of the garlic plant, is used instead of the bulb, and there is one crucial technique difference. The scapes are cut into 4 cm lengths, packed tightly into glass jars, and covered with the brine immediately while it is still boiling hot. The heat partially cooks the outer layer of each scape, which creates a clean, crisp snap when the scape is bitten, unlike the soft texture that results from the cold-pour method used for whole garlic. Whole black peppercorns included in the jar release their warmth and spicy aroma slowly into the liquid during the aging period, adding a dimension beyond the straightforward salt-and-acid base. The pickles are ready after a single day, but day three is when seasoning has penetrated to the center while the scapes still push back satisfyingly under the teeth. The brine can be drained, reboiled, and poured back over the scapes once during storage, which significantly extends shelf life by suppressing bacterial growth. On the Korean table, these sharp, vinegary pickles serve as a natural counterbalance to fatty meat dishes, cutting through richness and clearing the palate between bites.
