Goguma julgi kimchi is made from sweet potato stems, prepared by carefully peeling their tough, stringy outer skin to expose the elastic inner fiber, blanching briefly, then seasoning with gochugaru, anchovy fish sauce, minced garlic, and glutinous rice paste before being left to ferment. Once stripped of the outer skin, the stems retain only their springy, chewy core, which gives every bite a bouncy, almost springy resistance that sets this kimchi apart from leafy varieties. As the fermentation progresses, the seasoning works its way deep into the fibrous channels of each stem, building a well-balanced spicy-salty flavor throughout. Scallions bring a fresh herbal note, and onion rounds the sharp edges of the chili seasoning with natural sweetness. The peeling is time-consuming, but the distinctive texture rewards the effort. Made in peak summer when sweet potato stems are freshest, this kimchi is considered a seasonal treat.
Instructions
Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.
- 1Prep
Snap the end of 500 g sweet potato stems and pull upward to strip away the tough outer skin.
Cut the peeled stems into 5 cm lengths, then rub under running water to remove soil and loose fibers.
- 2Control
Bring plenty of water to a full boil, add the stems, and blanch over medium heat for only 2 minutes.
When the color brightens and the pieces bend slightly, move them straight into cold water.
- 3Season
Cool the stems completely in cold water so they keep their crunch, then drain and shake off excess moisture.
Sprinkle with 1.5 tbsp coarse salt, rest for 15 minutes, and rinse lightly to avoid harsh saltiness.
- 4Season
Slice 60 g onion thinly and cut 40 g scallions into easy bite-size lengths.
In a bowl, mix 3 tbsp gochugaru, 2 tbsp anchovy fish sauce, 1.5 tbsp garlic, 0.5 tsp ginger, and 2 tbsp sweet rice paste.
- 5Season
Add the drained stems, onion, and scallions to the seasoning and toss gently with fingertips.
Coat the fibrous grooves evenly, but keep the pressure light so the blanched stems do not snap or turn mushy.
- 6Finish
Taste the kimchi before packing; if it is too salty, balance it with a little more stem rather than extra rice paste.
Press into a container, ferment at room temperature for 6 hours, then refrigerate and serve after 1 day.

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 Coastal Hogfennel Kimchi
Bangpungnamul kimchi is a seasonal Korean kimchi made during spring by dressing coastal hogfennel in a chili-based seasoning paste. Bangpungnamul grows along coastal cliffs and mountain foothills, identifiable by its distinctive bitter-herbaceous aroma and mild sharpness. Traditional Korean medicine has long valued this plant for its properties in treating rheumatic conditions - its name literally combines the words for wind and prevention. The herb is lightly salted first to draw out excess moisture and soften its fibrous structure, then tossed with Korean chili flakes, anchovy fish sauce, soup soy sauce, minced garlic, and ginger. Sweet rice paste works as a binder, helping the thick seasoning cling evenly to each strand of herb rather than pooling at the bottom of the bowl. Sliced scallions add a crisp element that survives the marinating process intact. The herb's natural bitterness mellows considerably as lactic fermentation develops, producing a flavor profile unmistakably different from standard napa cabbage kimchi. One day at room temperature initiates fermentation without letting it run too far, after which refrigerated storage holds the kimchi at an ideal stage of acidity for two to three weeks.
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 Stir-Fried Sweet Potato Stems
Goguma julgi - sweet potato stems - are the above-ground vines of the sweet potato plant, a byproduct that Korean cooks transform into a summer namul rather than discarding. The most labor-intensive step is peeling each stem by hand, pinching the outer skin with a fingernail and pulling it away to reveal the tender core beneath. After blanching for two minutes and rinsing in cold water, the stems are stir-fried in perilla oil with garlic and seasoned with soup soy sauce. Perilla powder stirred in at the end thickens the remaining liquid into a nutty glaze. In season during summer, the stems are harvested from sweet potato fields before the tubers themselves are dug up.

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 Tofu Jeon (Golden Egg-Coated Pan-Fried Tofu)
Dubu-jeon is a Korean pan-fried tofu dish and a standard side dish in everyday home cooking as well as a fixture on ancestral rite tables. Firm tofu is sliced to about 1 cm thickness, seasoned with salt and pepper, dusted in a thin layer of flour to help the coating adhere, dipped in beaten egg, then fried on each side in a lightly oiled pan until the exterior turns golden and set. Pressing the tofu before cooking is the most important preparatory step: wrapping the slices in paper towels and placing a heavy object on top for at least fifteen minutes removes enough moisture to prevent the oil from splattering and allows the egg coating to bond tightly to the surface. Three to four uninterrupted minutes per side over medium heat are needed to develop an even golden crust without burning the egg; turning the pieces too often strips the batter away and leaves patches of bare tofu. The fried tofu is mild and nutty on its own, but a dipping sauce of soy sauce mixed with a small amount of vinegar and red pepper flakes adds salt, acidity, and heat that transform the simple base into something more complex. Eaten hot, the egg coating is thin and slightly crisp; as it cools the exterior softens while the interior remains tender.
Korean Hard Clam Radish Stew
Sweet radish broth meets briny hard clams in this clean, deeply flavored Korean stew that needs no stock -- just clams, radish, and 35 minutes. The radish goes into the pot first and boils for ten minutes to release its natural sweetness, building the foundation of the broth before the clams are added. Once the clams open, their concentrated marine flavor layers over the radish sweetness, creating a broth that is simultaneously clean and complex. Seasoning is kept minimal with soup soy sauce, and minced garlic is added only after the clams open so it cooks through without remaining sharp and raw. Thick-cut firm tofu absorbs the surrounding broth, acting as a sponge for the clam umami. Diagonally sliced cheongyang and red chilies go in last, contributing a mild heat and visual contrast to the pale liquid. Any clams that fail to open must be removed immediately to keep the broth free of grit. The stew demonstrates how two primary ingredients, clams and radish, can produce a layered, satisfying broth without anchovy or kelp stock. The cool, lingering aftertaste of the clams is a hallmark of this particular combination.

Korean Garlic Scape Kimchi
Maneul jong kimchi is a garlic scape kimchi made by lightly brining freshly harvested scapes, then dressing them in a seasoning paste of gochugaru, fish sauce, and plum syrup blended with pureed onion and pear. The scapes' sharp, piercing garlic aroma does not diminish through fermentation - it persists alongside the stems' crisp bite, delivering alternating pulses of heat and umami that build with each chew. Pear works into the base to introduce a fruit sweetness that blunts the chili intensity, while fish sauce provides the fermented backbone that grounds the entire kimchi. Trimming the fibrous bottoms before seasoning produces a more uniform snap throughout. Leaving the jar at room temperature for roughly two days allows the flavors to integrate and mellow into balance before refrigerating. This is a seasonal kimchi made only in spring when garlic scapes appear in the market, and its combination of raw green pungency and assertive garlic heat sets it apart from any other variety in the Korean kimchi repertoire.
Korean Crown Daisy Kimchi
Ssukgat kimchi is a fragrant seasonal kimchi that highlights crown daisy's herbal bitterness alongside chili flakes and sand lance fish sauce. The greens are salted for only seven minutes to preserve their delicate, tender texture, then dressed with a paste enriched by sweet rice flour for better adhesion. Plum extract balances the bitterness with gentle sweetness and acidity during fermentation. After two hours at room temperature followed by overnight refrigeration, the kimchi reaches its aromatic peak within a single day. Because the leaves bruise easily, gentle tossing during seasoning is essential to maintain their shape.
Korean Potato Salad (Creamy Mashed Potato Ham Cucumber)
Korean potato salad arrived through Japan's yoshoku tradition but developed its own distinct identity in Korean home kitchens. Potatoes are boiled until tender and mashed while still hot, but not to a perfectly smooth consistency - leaving some lumps gives the salad a dual texture of creamy mashed potato and soft, intact chunks that hold together when eaten. Diced ham is pan-seared briefly to render out excess fat before being incorporated, preventing the finished salad from becoming greasy. Cucumber is salted and squeezed to remove water, which keeps the salad from turning watery as it sits. Boiled carrot is mixed in for color and a mild sweetness. The dressing is mayonnaise adjusted with sugar and salt, resulting in a distinctly sweet-creamy profile that is noticeably different from Western versions of the dish. Chilling the assembled salad for at least one hour before serving allows the seasoning to equalize throughout the mixture, improving the flavor considerably compared to eating it straight away. The salad is served as a banchan alongside rice, and it is also commonly spread inside sandwiches.
