Kkakdugi is a staple Korean kimchi made from radish cut into 2 cm cubes, brined in coarse salt, then seasoned with gochugaru, salted shrimp, garlic, and ginger before fermentation. Salting draws out moisture from the cubes, creating a contrast between the damp interior and the snappy outer surface. Salted shrimp layers its briny seafood depth beneath the chili heat, and as fermentation progresses, the radish's natural sugars emerge to balance the spice with a clean sweetness. Brining time should be kept to thirty minutes to one hour since over-salting softens the radish and robs it of its characteristic crunch. Adding a small drizzle of perilla oil during the seasoning step deepens the nutty undertone of the finished kimchi, and substituting grated pear or apple for sugar provides a gentler, fruit-derived sweetness that integrates more seamlessly into the overall flavor. The accumulated brine at the bottom of the jar develops a refreshing tang that makes kkakdugi the essential companion to rich, milky soups like seolleongtang and gomtang.

6 steps
  1. 1
    Season

    Cut 1.2 kg radish into 2 cm cubes, place in a bowl, add 35 g coarse salt and 20 g sugar, and let sit for 30 minutes until moisture is drawn out.

  2. 2
    Season

    Pour off the liquid that collected from the salted radish once without rinsing the cubes, preserving the seasoning already absorbed.

  3. 3
    Season

    Add 70 g gochugaru to the radish and toss by hand until the cubes are deeply stained red, then add 25 g salted shrimp, 25 g minced garlic, and 8 g minced ginger.

  4. 4
    Season

    Cut 60 g green onions into 3 cm lengths, add to the bowl, and toss gently one more time so the seasoning is evenly coated over every piece.

  5. 5
    Season

    Taste and add a small amount of extra salted shrimp if more seasoning is needed, then pack tightly into an airtight container.

  6. 6
    Season

    Ferment at room temperature for 1 day then refrigerate; by days 2 to 3 the radish stays crisp while the gochugaru seasoning develops full depth.

Korean Seokbakji Radish Kimchi
Shared ingredient: korean radish Kimchi

Korean Seokbakji Radish Kimchi

Seokbakji is a traditional Korean radish kimchi in which large-cut radish cubes are salted for one hour, drained, and tossed with a seasoning of gochugaru, salted shrimp, minced garlic, ginger, and scallion pieces before being set aside to ferment. The size of the radish pieces is the most important factor in this kimchi - smaller cuts turn mushy during fermentation as salt and acid break down the cell structure, while large cubes maintain their firm, satisfying crunch throughout the entire maturation period. Salted shrimp here does far more than add salt: its fermented depth provides an umami backbone that gochugaru alone cannot deliver. After one day of fermentation at room temperature, two more days in the refrigerator allow lactic acid bacteria to develop a clean, refreshing sourness. The liquid that the radish releases during this process becomes a flavorful brine - this brine is one of seokbakji's most prized characteristics. Placed alongside a bowl of seolleongtang or gukbap, the cold, crunchy kimchi and its tangy liquid cut directly through the richness of the bone broth, refreshing the palate between spoonfuls. Compared to kkakdugi, seokbakji pieces are larger and more liquid-forward.

Korean Restaurant-Style Kkakdugi
Shared ingredient: korean radish Side dishes

Korean Restaurant-Style Kkakdugi

Sikdang-style kkakdugi is the cubed radish kimchi served as a complimentary banchan at virtually every Korean restaurant, standing alongside baechu-kimchi as a permanent fixture on the Korean table. Cutting Korean radish into chunky 2 cm cubes preserves crunch deep into the flesh even after salting and fermentation. Twenty minutes in coarse salt draws out excess moisture, and the cubes are then coated in a seasoning mixture of gochugaru, anchovy fish sauce, garlic, ginger, and sugar. The fish sauce lays the umami foundation that develops further during fermentation, while ginger suppresses the raw edge of the radish and leaves a clean finish. One day at room temperature initiates lactic acid fermentation, producing the characteristic tingle of an active kimchi, after which refrigeration allows the flavor to mature steadily over two to three weeks. Winter radish carries more natural sugar, so the added sugar can be reduced without sacrificing sweetness. In summer, shortening the room-temperature rest to half a day before refrigerating prevents the kimchi from becoming overly sour. It pairs particularly well alongside grilled pork belly, rice noodle soup, and earthenware pot rice soup, where its acidity cuts through the richness of the main dish.

Korean Braised Tofu with Kimchi
Serve together Steamed

Korean Braised Tofu with Kimchi

Dubu-kimchi-jorim is firm tofu braised with well-fermented aged kimchi in a sauce of soy sauce, gochugaru, minced garlic, and a pinch of sugar. The sharp acidity of the aged kimchi mellows during braising while its deep, fermented flavor remains fully intact. The tofu absorbs the chili-stained braising liquid like a sponge, carrying the kimchi flavor into every bite. Sugar takes the edge off the sourness just enough, and sesame oil stirred in at the end ties all the flavors together. Pressing the tofu before cooking prevents excess moisture from diluting the sauce, and pan-frying the pieces until golden on both sides before braising creates a firmer surface that holds together better. This dish is an efficient way to use kimchi that has sat in the refrigerator for months, as the stronger the sourness, the better suited it is for braising. Adding thinly sliced pork shoulder deepens the flavor considerably. It goes best spooned generously over a bowl of hot steamed rice.

Korean Ponytail Radish Kimchi

Chonggak kimchi is a traditional Korean kimchi made with whole young ponytail radishes salted for two hours, then coated in a paste of gochugaru, anchovy fish sauce, garlic, ginger, and scallions before fermenting. Blooming the chili flakes in fish sauce first softens their texture and intensifies the red color, and garlic and ginger are added afterward to build aromatic depth into the heat. Radish tops that are left too long turn fibrous, so trimming them short before seasoning keeps the kimchi crisp from root to leaf. One day at room temperature produces light carbonation and a cool, refreshing tang that signals the fermentation is alive. Refrigerating after that preserves the radish crunch and spicy umami for weeks. A year-round staple, this kimchi appears at Korean tables across every season.

Korean Seasoned Tofu Pouch Sushi (Yubu Chobap)
Rice Easy

Korean Seasoned Tofu Pouch Sushi (Yubu Chobap)

Yubu chobap consists of seasoned tofu pouches filled with sushi rice. The preparation begins by mixing rice vinegar, sugar, and salt into hot rice, using a cutting motion to preserve the grains. Sesame oil and toasted sesame seeds are added for aroma, along with finely diced carrot and cucumber to bring color and a crisp texture. The tofu pouches are lightly pressed and filled to about 80 percent of their capacity, preventing the skin from tearing during shaping. With each bite, the pouch releases a sweet and savory sauce absorbed by the tofu, which goes well with the seasoned rice. Since they are convenient to carry and eat by hand, they are popular for lunchboxes, quick snacks, and picnics.

Korean Spicy Grilled Gizzard Shad
Grilled Medium

Korean Spicy Grilled Gizzard Shad

Baendaengi yangnyeom gui is a Korean grilled fish dish in which scored gizzard shad are coated in a gochujang-based glaze and cooked over medium heat until caramelized. Scoring the fish achieves two things simultaneously: it lets the seasoning penetrate into the flesh rather than sitting only on the surface, and it severs the fine pin bones that run through the small fish so they become less noticeable when eating. The marinade combines gochujang, soy sauce, oligosaccharide syrup, gochugaru, and ginger juice. The ginger juice specifically targets the fishiness of the shad, neutralizing it while adding a warm, sharp note to the overall flavor. Sugar content in the glaze is high enough that high heat will char the coating before the fish cooks through, so medium heat is maintained throughout, with three to four minutes per side giving an even result. As the oligosaccharide heats, it caramelizes into a glossy amber coating that makes the finished fish look as good as it tastes. A scattering of toasted sesame seeds adds a nutty fragrance in the final step. Gizzard shad are small enough to be eaten whole, bones included, and the bold spicy-sweet glaze makes them as suitable alongside a bowl of rice as they are paired with soju at the table.

Korean Perilla Mushroom Hot Pot

Korean perilla mushroom hot pot is a hearty vegetarian dish made with shiitake, oyster, and enoki mushrooms, tofu, and bok choy simmered in a light vegetable stock. The cooking process starts by boiling the vegetable stock seasoned with soup soy sauce and minced garlic. Shiitake and oyster mushrooms are added first to build a deep umami base. Tofu, enoki mushrooms, and bok choy are then arranged on top and simmered until the vegetables are tender. To finish, ground perilla seed powder is gently stirred into the broth at the very end, which prevents the soup from becoming gritty while releasing a rich, nutty aroma and creating a naturally thick texture. This hot pot delivers a satisfying combination of earthy mushrooms, soft tofu, and crisp bok choy, offering a comforting meatless meal.

Korean Radish Greens Kimchi

Mucheong kimchi is made from the leafy greens and stems of Korean radish, cut into 5 cm lengths, salted in coarse brine, then coated in a paste of sweet rice flour, gochugaru, anchovy fish sauce, minced garlic, ginger, and onion. The thick, fibrous stems grip the seasoning and hold up through fermentation without turning mushy, keeping a firm chew even after weeks in the refrigerator. Sweet rice flour acts as a glue that prevents the coating from sliding off the stems as the kimchi ages. Anchovy fish sauce lays down a deep seafood umami as the base layer, while onion moderates the chili heat with natural sweetness. The greens are a practical use of the entire radish rather than just the root, and the finished kimchi works beyond the banchan role: torn into pieces and added to siraegi soup, it enriches the broth; stirred into doenjang jjigae, it deepens the fermented soybean flavor with another layer of fermented complexity.

Korean Scallion Kimchi (Whole Stalk Anchovy Shrimp Paste)

Jjokpa kimchi is a traditional Korean scallion kimchi made by briefly brining whole scallions in coarse salt, then coating them from root to tip with a seasoning paste of anchovy fish sauce, fermented shrimp, gochugaru, and sweet rice flour paste. Using both anchovy fish sauce and salted shrimp together is intentional: the two condiments each carry a different profile of seafood umami, and combining them produces a more complex, layered depth than either alone could achieve. The sweet rice flour paste acts as a binder, adhering the seasoning evenly to the surface of each scallion and keeping it in place as moisture releases during fermentation. Without this paste, the pickling liquid would dilute the coating and the flavor would fade over time. The white bulb sections of the scallion hold their crunch through the brining and fermentation process while absorbing the spice of the gochugaru, and the green tops wilt to a silky texture that releases the scallion's characteristic sweet, pungent aroma. After six hours at room temperature followed by a day of refrigeration, the seasoning has fully penetrated the scallion and the kimchi is ready to eat alongside grilled pork belly or bossam. After three or more days of fermentation, a gentle lactic acidity develops that makes the kimchi equally useful as an ingredient in stews or stir-fries.

Braised Korean Radish (Soy Garlic Slow-Cooked Side)

Mu-jjim is a Korean braised radish dish where thick-cut Korean radish is simmered slowly in a covered pot with soy sauce, sugar, and garlic. The radish absorbs the seasoned liquid as it cooks, turning translucent from edge to center and developing a natural sweetness that balances the saltiness of the soy base. A drizzle of sesame oil at the end adds a nutty fragrance, and a single sliced green chili contributes a mild kick to the finish. Despite the short ingredient list, this banchan pairs naturally with rice at any meal and holds up well as a make-ahead side throughout all seasons. Keeping the heat at medium or below for at least twenty minutes allows the radish to soften fully and take in the seasoning without becoming mushy.
