Key ingredients
Core cooking flow
- 1 Peel 700 g kohlrabi deeply enough to remove the tough outer fibers, then cut it into 1.5 to 2 cm cubes.
- 2 Place the kohlrabi in a bowl, sprinkle evenly with 1.5 tbsp coarse salt, and brine for 20 minutes.
- 3 When the cubes bend slightly and look wet on the surface, rinse them once under running water.
Kolrabi kimchi is made by cutting kohlrabi into 2 cm cubes, brining them in coarse salt, then mixing with gochugaru, fish sauce, minced garlic, and plum syrup before fermentation. Kohlrabi has lower moisture content and a denser cellular structure than Korean radish, which means its crunch holds up through days of fermentation without softening into mush. The brining step draws internal moisture out of the kohlrabi while driving salt evenly into the tissue, and this stage must be completed thoroughly so that seasoning can penetrate all the way through during fermentation. Kohlrabi's natural sweetness creates a clear contrast against the heat of gochugaru, adding textural depth to the flavor profile. Fish sauce builds the savory fermented foundation, while plum syrup contributes both acidity and sweetness to keep the overall seasoning in balance. Eaten immediately after mixing, the kimchi tastes fresh and light, similar to a dressed salad. After one to two days at room temperature or three to four days in the refrigerator, the umami deepens noticeably and the characteristic tang of fermentation emerges. It works well as a substitute for kkakdugi alongside rice and grilled meats.
Instructions
Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.
- 1Season
Peel 700 g kohlrabi deeply enough to remove the tough outer fibers, then cut it into 1.5 to 2 cm cubes.
Keep the pieces even so the brine and seasoning penetrate at the same pace.
- 2Season
Place the kohlrabi in a bowl, sprinkle evenly with 1.5 tbsp coarse salt, and brine for 20 minutes.
Turn it once halfway through so the bottom pieces release moisture and season as evenly as the top.
- 3Step
When the cubes bend slightly and look wet on the surface, rinse them once under running water.
Drain in a sieve and press gently; avoid hard squeezing because broken edges soften faster during fermentation.
- 4Season
In a large bowl, first mix 2.5 tbsp gochugaru, 1 tbsp minced garlic, 1.5 tbsp fish sauce, and 1 tbsp plum extract syrup.
Stir until the flakes look damp, which prevents dry clumps from sticking to one spot.
- 5Season
Add the drained kohlrabi to the seasoning and toss from the bottom upward with a gloved hand or spatula.
Once every cube is red and glossy, cut 40 g scallions into 3 cm lengths and add them.
- 6Step
Fold gently so the scallions do not snap, then pack the kimchi into an airtight container and press out air pockets.
Eat it fresh for a light crisp taste, or refrigerate 3 to 4 days for deeper umami.

Korean Cabbage Kimchi (Crunchy Green Cabbage Kimchi)
Yangbaechu kimchi is a Korean cabbage kimchi made by salting green cabbage and tossing it with chili flakes, fish sauce, and minced garlic. The thicker leaves and lower moisture content of green cabbage compared to napa cabbage result in a noticeably crunchier texture that persists through fermentation. The natural sweetness of cabbage softens the heat from the chili seasoning, while carrot and scallion pieces add color and freshness. Six hours of fermentation at room temperature followed by refrigeration lets the tanginess develop gradually. It serves as a lighter alternative when traditional napa kimchi feels too heavy.
Korean White Kimchi (Non-Spicy Napa Pear Fermented)
Baek kimchi is a Korean white kimchi made without gochugaru, producing a completely non-spicy, clear-broth fermented vegetable. Napa cabbage is salted and wilted, rinsed, then layered with julienned radish, sliced garlic, and ginger tucked between the leaves. Pureed pear serves as a natural sugar source that feeds fermentation, while dried jujubes add a subtle background sweetness to the brine. Salted water is poured over the assembled cabbage, the container is sealed, and after one day at room temperature the kimchi moves to the refrigerator for a slow ferment. Without chili heat, the flavor centers on the clean lactic acidity that develops over time, balanced by the natural sweetness of pear and jujube and the warm bite of garlic and ginger dissolved into the brine. The fermentation is slower than standard kimchi, reaching optimal taste at two to three weeks. It is eaten with its brine, either on its own or as a palate-clearing side alongside fatty meat dishes. Before chili peppers were introduced to the Korean peninsula in the late sixteenth century, kimchi without gochugaru was the standard form, and baek kimchi is considered the closest modern equivalent to those pre-chili preparations.
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 Kohlrabi Soy Pickle
Kohlrabi jangajji is a Korean soy pickle made by thickly peeling kohlrabi, cutting it into 2 cm cubes, and submerging the pieces with garlic and dried chili in a pickling brine of boiled soy sauce, vinegar, and sugar. Kohlrabi's dense cellular structure absorbs the brine slowly, holding a firmer crunch and more pronounced sweetness than radish over several days of pickling. The soy sauce's savory depth and the vinegar's acidity draw out the kohlrabi's natural sugars, while dried chili contributes a subtle warmth and color to the brine. Pouring the brine only after it has fully cooled preserves the kohlrabi's crunch, as hot liquid softens the cell walls and reduces the staying power of the pickle. This pickle works well as a palate cleanser alongside grilled meat or samgyeopsal, cutting through richness with its tart, sweet bite, and stored in the refrigerator it holds its crisp texture for two to three weeks. Adjusting the ratio of vinegar to sugar in the brine shifts the pickle toward more sour or more sweet depending on preference.

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.
Korean Grilled Bellflower Root
Bellflower root is shredded lengthwise, soaked in salted water, and blanched for one minute to draw out its characteristic bitterness without eliminating it entirely. A ten-minute soak in a sauce of gochujang, gochugaru, soy sauce, oligosaccharide syrup, garlic, and sesame oil seasons the root before it hits a medium-heat pan for three to four minutes per side. The result has a crisp, crunchy bite - distinct from any other vegetable - with a red-glazed surface that carries moderate heat. Open-flame grilling adds a smoky dimension that pairs well with the spicy coating, and sesame seeds provide a finishing touch.
Korean Silken Tofu Seafood Stew
Sundubu haemul jjigae is a seafood soft tofu stew that combines silken tofu with shrimp and Manila clams in an anchovy stock seasoned with gochujang and Korean chili flakes. The aromatics are stir-fried in sesame oil first to build a deeper base before the stock is added. As the shrimp and clams cook through, they release their own briny juices into the spicy broth and push the umami noticeably higher. An egg cracked in at the end binds gently with the silken tofu, adding richness and a slight body to the broth. Deveining the shrimp and removing the back intestine keeps the flavor clean, and soaking the clams in lightly salted water beforehand purges any sand that would otherwise cloud the stock.

Korean Fermented Kale Kimchi
Kale kimchi is made by wilting kale leaves in coarse salt, then tossing them with julienned radish, scallions, gochugaru, soup soy sauce, and pear puree before fermenting. The kale's strong green flavor mellows during fermentation while its sturdy leaf structure maintains a satisfying chew, and the radish strips add a crisp counterpoint to the soft seasoning. Pear puree wraps around the chili heat with fruit sweetness, and soup soy sauce anchors the seasoning with a quiet umami depth. Made using the same technique as napa cabbage kimchi but carrying kale's distinctive slight bitterness, this version adds a layer of complexity and nutritional density to the traditional format. Kale requires less salting time than napa cabbage, and weighting it down evenly during the process ensures consistent wilting throughout the batch.
Korean Kimchi Pancake
Kimchi-jeon is a Korean savory pancake made by chopping well-fermented kimchi into small pieces, mixing it into a batter of pancake flour, kimchi brine, and chili flakes, then frying the batter in oil until both sides turn golden and crisp. Using kimchi brine instead of plain water is the central technique: the lactic acid from fermentation adds a tangy depth to the flour base that water simply cannot provide. The batter consistency varies with how wet the kimchi is, so the target is a texture that runs slowly rather than puddles, which usually requires less liquid than might seem necessary. Neutral cooking oil or perilla oil suits the flavor profile better than olive oil, preserving the characteristic savory aroma of Korean pan-fried foods. Four minutes on the first side over medium-high heat followed by three minutes after flipping produces a crust that is genuinely crisp at the surface while the inside stays moist from the kimchi's own liquid. Pressing lightly with a spatula before flipping helps confirm that the underside has set firmly enough to hold its shape. A pancake that is too thin burns before it develops flavor, and one that is too thick leaves the interior underdone. Kimchi-jeon is at its best immediately off the pan, but a brief return to a dry skillet restores most of the crispness when reheating leftovers.
Korean Fresh Cabbage Kimchi
Geotjeori is kimchi's immediate cousin - raw napa cabbage dressed in gochugaru seasoning and eaten right away without any fermentation. The cabbage is salted for about twenty minutes to draw out moisture and soften the texture slightly, then squeezed dry and tossed with red pepper flakes, anchovy fish sauce, minced garlic, minced ginger, sugar, and a finishing drop of sesame oil. The brief salting pulls just enough water from the leaves to let the seasoning coat them evenly while keeping the cabbage noticeably crisper than fermented kimchi. Without the lactic acid produced during aging, the flavor profile is fresher and more direct - the heat of the gochugaru and the savory depth of the fish sauce come through cleanly rather than sitting under layers of fermented complexity. Geotjeori is best eaten the day it is made and should be used within a day or two if refrigerated. Koreans pair it with grilled pork belly, alongside doenjang-jjigae, or as a quick substitute when the aged kimchi jar runs empty.
