Korea's Fruit Snack Moment Is Far From Over — It Just Changed Shape
If you visited Seoul in 2023, you know the sound: a sharp, glassy crack as teeth broke through a sugar shell around a grape or strawberry, the kind of ASMR crunch that was designed for a phone camera. Tanghulu — sugar-coated fruit skewers borrowed from northern Chinese street food tradition — swept through Korean social media with a velocity that few food trends have matched. At its peak, the country's largest tanghulu chain reportedly grew from roughly 50 outlets to over 300 within a single six-month period. More than 90 percent of tanghulu-related trademarks filed in Korea were registered in 2023 alone. And then, as Korea Times reported in early 2026, by May 2024 the craze had begun to wane sharply — shop closures followed, consumer health concerns about excessive sugar intake accelerated the retreat, and a market that had expanded at an almost comically unsustainable pace contracted back toward reality. The tanghulu era was over.

What comes next, though, is the more interesting question. Korea's relationship with viral fruit snacks did not end with tanghulu — it evolved. The drivers that made tanghulu explode in the first place are still fully operational: TikTok and Instagram Reels continue to amplify visual food content with extreme speed, young Korean consumers remain intensely engaged with the aesthetics of what they eat, and Myeongdong's street food corridor remains one of the most effective real-world launching pads for a food trend to go from local curiosity to global conversation. What has changed is the direction. The market has moved away from maximum sugar toward more nuanced, more "photogenic but also defensible" territory — snacks that look extraordinary and taste complex enough to justify the content without triggering the health backlash that ultimately killed tanghulu's momentum.
Why Tanghulu Fell — and What That Tells You About What's Next
Understanding the tanghulu collapse is essential to predicting its successor, because Korea's viral food cycles follow patterns that are now well enough documented to be genuinely instructive. Korean viral food trends tend to follow a predictable arc: rapid rise driven by social media amplification and scarcity mechanics, followed by intense hype, saturation from low-barrier-to-entry competitors flooding the market, and then decline triggered either by health concerns, novelty fatigue, or both. Tanghulu hit all four stages within roughly eighteen months.
The health criticism was particularly damaging because it was specific and hard to argue with. Health experts raised concerns about the sheer volume of refined sugar in a standard tanghulu serving, and those concerns landed with the exact demographic — health-conscious millennials in their 20s and 30s — who had driven the trend in the first place. Consumer sentiment shifted toward what Korean food media was already calling "zero sugar" alternatives and "adult-taste" formats: desserts that were complex, bitter-edged, or fermented rather than maximally sweet. The Korea Herald noted in January 2026 that even the dominant trend of early 2026 — the dujjonku, or Dubai Chewy Cookie — was valued primarily for its texture (what Koreans call kkudeok kkudeok, meaning dense and satisfyingly chewy) rather than for sweetness alone. Texture has replaced raw sugar as the primary driver of Korea's viral food psychology. Any fruit snack that wants to break through in 2026 needs to win on texture and visual identity, not just sugar content.
Chapssaltteok Gets a Fruit Upgrade
The most credible candidate for tanghulu's successor in the fruit snack space is a format that Korea has known for centuries but that is currently being radically reinterpreted: chapssaltteok, the glutinous rice cake that functions as Korea's version of Japanese mochi. Traditional chapssaltteok is filled with sweetened red bean paste and carries a soft, dense chew that operates on a completely different register from the candy-shell crunch of tanghulu. What is happening now is that artisan vendors — primarily in the Seongsu and Hongdae café districts, but increasingly in Myeongdong as well — are producing chapssaltteok stuffed with fresh seasonal fruit: whole strawberries, sliced mango, muscat grapes, and cream cheese or whipped cream combinations that create a cross-section visual when the rice cake is cut or bitten open.
The appeal is multidimensional in a way that tanghulu never managed to be. First, the visual: a freshly cut fruit chapssaltteok reveals a jewel-bright interior — vivid red strawberry or amber mango against white cream inside a delicate rice cake exterior — that photographs with the same immediate intensity as the tanghulu's glossy sugar shell but reads as considerably more sophisticated. Second, the texture: the combination of chewy rice cake, cold cream, and yielding fresh fruit delivers the kkudeok kkudeok quality that Korea's current taste landscape rewards, all without the sugar-shock that ended tanghulu's moment. Third, the health positioning: rice cake is a traditional Korean ingredient with generational credibility, fresh fruit is inherently defensible, and the overall format is perceived as meaningfully lighter than a deep sugar coating. Vendors at Gwangjang Market and Seongsu foodie stops have been tracking strong repeat purchase behavior on fruit chapssaltteok — the mark of something that has crossed from novelty into genuine preference.

The format's relationship with Korean food culture also gives it more durability than tanghulu ever had. Tanghulu was, at its core, a borrowed concept — a Chinese street food that Korean consumers adopted and accelerated but that never acquired the kind of cultural rootedness that sustains a trend past its initial social media peak. Chapssaltteok is native. The rice cake is embedded in Korean celebration culture, traditional markets, and generational memory in a way that makes the premium fruit version feel like an upgrade of something loved rather than the adoption of something foreign. That distinction matters enormously for long-term trend survival.
Hwachae: From Traditional to Trending
While chapssaltteok is building credibility from the artisan side, hwachae is approaching the viral fruit conversation from a completely different angle. Hwachae — literally "flower water" in Korean, referring to traditional fruit punch made with fresh seasonal fruit, strawberry milk, and carbonated soda — has existed in Korean culture for centuries and has been a staple summer drink in traditional households for generations. What is new is its presentation and its audience. Starting around 2024 and accelerating sharply into 2026, hwachae has been reimagined as a spectacular, oversized, fully customizable fruit bowl experience sold in large clear cups that show off layers of watermelon cubes, strawberries, blueberries, dragonfruit, and mango floating in pink strawberry milk with Chilsung cider providing fizz at the base.
The visual impact is immediate and substantial — the large format cup filled with dramatically colorful fruit in a pink-tinted liquid is one of the most instantly appealing food photographs being taken on the streets of Seoul right now. More importantly, hwachae achieves the health positioning that tanghulu could not: it is made of fresh fruit, its liquid base is more dilute than a sugar syrup, and it functions as hydration as much as dessert — a fact that Korean consumers, increasingly attentive to functional food narratives, find genuinely appealing. The customizability adds a participatory element: vendors in Myeongdong are beginning to offer hwachae builds where customers select their own fruit combinations, creating a moment of personalization that generates additional content and social engagement before anyone has even taken a sip.

Hwachae's trajectory in 2026 has the characteristics of a trend with genuine staying power. Unlike tanghulu, it did not emerge from nowhere — it is a repackaging of something culturally familiar into a format optimized for the current moment. Unlike yogurt ice cream, which peaked in early 2024 and began to decline as market saturation set in, hwachae's low-cost-of-entry ingredients and high visual-impact-per-dollar ratio make it easier for vendors to maintain quality without racing to the bottom on pricing. The delivery app integration — multiple TikTok creators documented ordering hwachae for late-night delivery in Seoul — has also given it a domestic life beyond the street food corridor, extending its reach into occasions where tanghulu, a snack defined by its immediate fresh-baked quality, could never follow.
The Freeze-Dried Factor: Binghulu and the Zero-Sugar Fork
There is a third entrant in this conversation that addresses the sugar concern most directly: freeze-dried fruit snacks, and specifically a format called binghulu, which applies the visual and structural logic of tanghulu but replaces the sugar syrup coating with carbonated liquid — sparkling water or zero-calorie beverages — that causes the freeze-dried fruit to crackle and expand in a way that delivers a comparable sensory drama to the original tanghulu crunch without the refined sugar. The format has been circulating on TikTok outside Korea for long enough that it carries pre-built awareness, and Korean street vendors in Myeongdong and Hongdae have been testing binghulu variations that use imported sparkling beverages as the "coating" medium.
The freeze-dried format also appeals to the growing market for snacks that can be packaged, gifted, and carried without the immediate deterioration that makes fresh-format street food difficult to merchandise beyond the moment of purchase. Freeze-dried strawberries and muscat grapes retain the intense color that made tanghulu photographically compelling, they have a satisfying airy crunch, and they position as a naturally concentrated fruit product rather than a sugar delivery vehicle. Korean convenience store chains, which have proven remarkably effective at taking street food trends and institutionalizing them for mass consumption, have already begun stocking freeze-dried fruit snack ranges. That kind of retail channel confirmation is typically a signal that a format has moved from emerging to established.
What Sticks and What Doesn't: The 2026 Forecast
Korea's food trend analyst community — and there genuinely is such a community, operating across food media, consulting firms, and social platforms — has noted that the trends with the longest lifespans in the Korean market share specific traits: they have a native or naturalized cultural foundation, they reward texture as much as flavor, they photograph distinctively at every stage from preparation to first bite, and they can be scaled across price points from street cart to premium café without losing their identity. Tanghulu, evaluated against those criteria, fails on the first count. The Dubai Chewy Cookie, the dominant trend of early 2026, scores highly on texture and photography but may face saturation pressure from the same low-barrier-to-entry dynamics that collapsed tanghulu.
Fruit chapssaltteok, hwachae, and freeze-dried formats all score better across the board. None of them has yet achieved the explosive single-moment virality that tanghulu managed at its peak, but that might actually be an advantage. In Korea's current trend economy — which one observer memorably described as "a market stress test" — the items that endure are increasingly those that build steadily rather than spike instantly. The next dominant fruit snack in Seoul is probably already being made somewhere on the Myeongdong food street or in a Seongsu café right now. What it looks like depends on which format captures a single viral moment that translates correctly across TikTok, Instagram, and YouTube Shorts within the next season. Which of these three — fruit chapssaltteok, hwachae, or binghulu — would you put your money on?
