Seori-kongguksu-cup serves chilled black soybean broth over thin somyeon noodles in a cup-sized portion, a cool summer street food built for hot weather. The broth is made by blending boiled black soybeans with milk and cold water, then pressing through a fine strainer for a silky, lump-free consistency. Black soybeans give the broth a grayish hue distinct from the ivory-colored broth made with ordinary yellow soybeans, and the flavor is noticeably richer and more intensely nutty, with a clean finish rather than a heavy aftertaste. Cooking the soybeans fully and letting them cool before blending is important because heat drives off the aromatic compounds that give the broth its characteristic fragrance. Sliced cucumber, cherry tomatoes, and ice cubes go on top, the vegetables adding crunch and color contrast while the ice keeps the broth cold so the soybean flavor stays sharp and defined. Somyeon noodles are boiled and rinsed several times in cold water to strip off surface starch, which would otherwise cloud the broth and make the noodles clump. The result is a simple, satisfying bowl where every element has a clear role.
Instructions
Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.
- 1Control
Cook the 180 g soaked black soybeans over medium heat for about 25 to 30 minutes, until they crush easily between your fingers.
Skim off only loose floating skins, then cool the beans completely before blending.
- 2Season
Add the cooled beans, 450 ml cold water, 120 ml milk, and 4 g salt to a blender.
Blend for at least 1 minute, until the broth turns grayish and no coarse bean pieces remain.
- 3Control
Press the soybean broth through a fine strainer to reduce graininess and make it silky.
If you are not serving right away, chill it for 1 hour so the nutty flavor settles and deepens.
- 4Control
Drop 180 g somyeon noodles into boiling water and cook over medium high heat for 3 to 4 minutes.
If the pot foams up, add a small splash of cold water to keep the noodles from overcooking.
- 5Heat
Rinse the cooked noodles several times in cold water, rubbing gently to remove surface starch.
Drain well when they no longer feel slippery and the strands feel springy, so the broth does not turn watery.
- 6Finish
Divide the drained noodles among cups and pour the cold soybean broth over them.
Top with 60 g cucumber, 6 cherry tomatoes, and 8 ice cubes, then serve immediately while the broth is cold and clean tasting.

Korean Yuja Chicken Cold Somyeon
Yuja chicken naeng somyeon is a Korean cold noodle dish served in a clear chicken-radish broth brightened with yuja (citron) syrup. The broth is chilled before serving, and its combination of mild chicken flavor and floral citrus aroma sets it apart from other cold noodle soups. Shredded poached chicken breast is placed on top of the cold somyeon along with cucumber or cherry tomatoes. The broth is deliberately kept lean, with no heavy oils. If the broth is prepared in advance, the final assembly takes under 30 minutes.
Korean Dongchimi Cold Naengmyeon
Dongchimi naengmyeon is a cold noodle dish built around the fermented brine of dongchimi, a water-based winter kimchi made with whole radish. The brine is blended with chilled beef or chicken stock, creating a broth that looks deceptively simple but carries a layered complexity from months of fermentation. The lactic acidity of the dongchimi water is not sharp or aggressive - it is long and clean, acquired through slow fermentation rather than vinegar shortcut. At very cold temperatures, just at the point of forming a thin skin of ice on the surface, the radish-derived fragrance in the broth becomes most vivid and refreshing. Thin slices of boiled beef add a lean, meaty backbone that anchors the acidity without competing with it. Julienned Korean pear brings gentle sweetness and crunch, and half a boiled egg rounds out the bowl with richness. Cutting the noodles several times with scissors before placing them in the bowl keeps them from clumping in the cold and allows the broth to reach every strand from the first bite.
Candied Sweet Potato
Goguma mattang is a Korean candied sweet potato snack made by cutting peeled sweet potatoes into large chunks and deep-frying them at 170 degrees Celsius until the interior turns floury and soft. A syrup of sugar, corn syrup, water, and a measured splash of soy sauce is cooked separately until large, foamy bubbles form - the visual cue for adding the fried sweet potatoes. Everything must be coated within thirty seconds to lock in a thin, glass-like caramel shell that crisps and turns translucent as it cools. The soy sauce shifts the flavor from purely sweet to a rounded, slightly savory depth. Pre-draining surface moisture from the cut sweet potatoes reduces oil splatter during frying and helps the syrup grip the pieces evenly. Black sesame seeds are scattered over the finished pieces for a toasted, nutty note, and each piece is spread individually on parchment paper while still warm so they cool without sticking together.
Korean Cold Buckwheat Noodles
Mul naengmyeon is a Korean cold noodle dish in which firm buckwheat noodles are served in a clear broth chilled to a near-slushy, half-frozen state. Placing the broth in the freezer for about an hour until thin ice crystals form at the surface maximizes the cold shock on the first sip, which is central to the dish's appeal. The noodles are boiled briefly and then rubbed under cold running water to strip away excess buckwheat starch and its distinct raw odor, with a final rinse in ice water to firm the strands and restore their spring. Julienned cucumber and thinly sliced pickled radish add recurring crunch that offsets the smooth, icy broth, while a halved hard-boiled egg provides a rich, creamy yolk that anchors the otherwise lean liquid. Vinegar stirred in at the table sharpens the overall flavor with bright, clean acidity, and Korean mustard dissolved in a small spoonful of broth adds a penetrating sinus heat that cuts through the cold. The dish traces its origins to Pyongyang-style cold noodles, but regional variations using beef, chicken, or dongchimi radish kimchi broth as the base produce noticeably different flavor profiles, all bound by the same insistence on extreme coldness and a long, chewy noodle.

Korean Seasoned Sea Grapes Salad
Kkosiraegi-muchim is a tangy, low-calorie banchan made from kkosiraegi, a red algae seaweed whose thin, noodle-like strands snap with a distinctive crunch that no other seaweed can replicate. Blanching must not exceed twenty seconds, as anything longer collapses the characteristic texture, so a timer is essential. The seaweed goes straight from the boiling water into cold water to stop the heat and lock in elasticity. The dressing brings together gochugaru, soup soy sauce, vinegar, maesil-cheong, garlic, and sesame oil; the green plum extract layering in a fruity acidity that lifts the dish beyond simple sour-spicy flavoring. Julienned cucumber threaded through the seaweed strands provides a crisp, garden counterpoint to the oceanic depth. At roughly 72 kilocalories per serving with high dietary fiber content, this banchan appears frequently in Korean diet meal plans because it satisfies without adding much to the calorie count. Eating it promptly after seasoning prevents the cucumber from releasing water and diluting the dressing. Served cold in summer, it doubles as a refreshing side that pairs well with grilled meat or plain rice.
Kongguksu (Korean Cold Soy Milk Noodles)
Kongguksu is a Korean cold noodle dish in which thin somyeon noodles are served in a chilled broth made entirely from blended soybeans. Cooked white soybeans are peeled as thoroughly as possible to reduce any bitterness, then blended with cold water, sesame seeds, and salt until the mixture is smooth and creamy. The resulting soy broth is refrigerated until genuinely cold before use -- adding ice directly to the bowl would thin it out, so proper chilling in advance is the standard approach. Somyeon noodles are boiled until just cooked through, then rinsed vigorously under cold running water and briefly submerged in ice water to firm up their texture before being placed in the serving bowl. The cold soy broth is poured generously over the noodles, and julienned cucumber is arranged on top for color and crunch. Seasoning is personal: some eat it with salt only, others stir in a small amount of sugar. Straining the broth once through a fine mesh sieve eliminates any remaining gritty bits and gives the finished soup a noticeably silkier mouthfeel. High in plant protein and relatively light on the stomach despite its richness, it is exactly the kind of cold dish that makes summer heat more bearable. Black soybeans blended in alongside white ones deepen both the color and the toasty, nutty flavor.
Korean Baekseju Herbal Rice Wine
Baekseju is a traditional Korean herbal rice wine produced by infusing a fermented glutinous rice base with twelve medicinal ingredients including fresh ginseng, jujubes, ginger, wolfberry, and cinnamon, then sweetening the result with honey. The brand was launched by Kooksoondang in 1992 and has since become the dominant commercial representative of the yakju category - herbal Korean rice wine - in mainstream retail. The foundation is glutinous rice fermented with nuruk, a traditional wheat and grain-based starter culture that produces a mildly sweet, relatively low-acid alcohol. Fresh ginseng steeped in that fermenting liquid contributes its characteristic bitterness and earthy depth, which sit on top of the rice sweetness rather than replacing it. Jujubes lend a faint reddish tint and a dried-fruit sweetness that stays in the background, while ginger delivers a slow, peppery warmth that registers at the back of the throat after swallowing. The honey is added after primary fermentation has proceeded far enough that the yeast population is declining; this preserves residual sugar in the finished wine rather than having it fully fermented out. That residual sweetness is central to Baekseju's flavor identity and distinguishes it from drier yakju styles. Alcohol content sits around thirteen percent, comparable to a medium-bodied grape wine. The liquid is filtered clear and appears golden, substantially more transparent than unfiltered makgeolli. Served cold, the herbal complexity recedes and the wine drinks crisp and refreshing; at room temperature, the ginseng bitterness and jujube sweetness become more pronounced with each sip. It pairs well with fatty or strongly flavored Korean dishes - grilled pork belly, braised spicy chicken - where the medicinal herbaceousness cuts through the richness.

Korean Jjajang Tteokbokki
Jjajang tteokbokki simmers chewy rice cake sticks in a sauce of black bean paste (chunjang) stir-fried with ground pork, onion, and cabbage. The critical first step is pre-frying the chunjang in a generous amount of oil before adding any other ingredients: raw black bean paste carries a flat, slightly bitter taste, but several minutes of stirring in hot oil transforms it, removing the harsh edge and developing the characteristic deep, roasted sweetness that defines the dish. As the sauce reduces and thickens, it clings heavily to each rice cake, delivering an intense hit of savory black bean flavor with every bite. Unlike gochujang-based tteokbokki, there is no chili heat present at all, making this a version accessible to those who find standard tteokbokki too spicy. The ground pork renders fat into the sauce as it cooks, adding richness and making the sauce glossier and heavier in body. Julienned cucumber scattered on top at serving provides a fresh, crunchy contrast that cuts through the richness of the black bean sauce and brightens the overall flavor of the bowl.
Korean Mala Cup Tteokbokki
This cup-style tteokbokki blends gochujang with mala sauce to combine Korean chili heat and the numbing tingle of Sichuan peppercorn in a single dish. Rice cakes and fish cake go into the pot with the sauce, then cook over medium heat for six to seven minutes with constant stirring as the liquid reduces into a thick, clinging glaze that coats each piece heavily. Stopping to stir is not optional: the rice cakes stick and scorch on the bottom without continuous movement. Sliced green onion goes in at the end for fragrance. Because mala sauce saltiness varies considerably between brands, beginning with one tablespoon and tasting as you add more prevents overseasoning. Additional gochugaru raises the chili heat independently of the numbing sensation, while increasing the mala sauce proportion amplifies the tingle. The format mirrors the convenience-store cup tteokbokki experience and requires minimal equipment, making it a fast option when few tools are available.
Korean Kimchi Jeon Cup (Kimchi Pancake Cups)
Kimchi jeon cups are small Korean pancakes made from a batter of pancake mix, water, kimchi brine, finely chopped aged kimchi, green onion, and Cheongyang chili, pan-fried into rounds and served standing upright in paper cups. Adding kimchi brine directly to the batter is the key step that separates these from a standard kimchi pancake: the fermented liquid spreads its salt and umami through every part of the batter, so the flavor is more intense and consistent than when kimchi is simply folded into a neutral base. A generous amount of oil in the pan and medium heat together crisp the edges into a fried shell while the center stays slightly soft and chewy. The Cheongyang chili adds a sharp, clean heat on top of the kimchi acidity, keeping the flavor lively. A thicker batter consistency than normal pancakes is necessary for this format: thin batter flops and collapses once stood upright in a cup, while a stiffer mix holds the round shape without bending. The hand-held cup format references pojangmacha culture, the covered street-stall tradition, and the pancakes are typically dipped in soy sauce or a vinegar-gochujang sauce.
