Korean street food that survived decades on the sidewalks of Seoul — and then exploded globally when Squid Game introduced it to 111 million households.
In Korea, it is called ppopgi, and for decades it was the domain of street vendors near school gates — a treat for children, sold for a few hundred won from improvised stalls on city sidewalks. The process is hypnotic to watch: sugar and baking soda are melted in a small metal ladle over a tiny flame until they transform into a golden, caramelized foam, then poured onto a flat surface and pressed thin with a mold. Once cooled to a brittle disc, it is stamped with a shape — a star, a circle, a triangle, an umbrella. The game: carve the shape from the candy using only a needle or pin without breaking it. Success meant a free candy from the vendor. Failure meant eating the broken pieces anyway, which was not really losing. This was an ordinary Korean childhood ritual, invisible to the outside world, practiced in neighborhoods across Seoul, Busan, and Daegu from the 1960s through the 1990s before the vendor culture began to fade. Then, in September 2021, Netflix's Squid Game premiered and became the most-watched series in the platform's history, reaching 111 million households in its first month. The third episode's game — in which characters compete to carve the shape from their dalgona without breaking it, under lethal stakes — immediately went viral globally. Within days, the DalgonaCandyChallenge was trending on TikTok in dozens of countries. Koreans who remembered ppopgi as childhood nostalgia watched the world suddenly discover something they had always known. Dalgona is a perfect capsule of Korean street food culture: simple, cheap, communal, and rooted in a specific time and place. Seoul's pojangmacha — the covered street food stalls that have been serving late-night Koreans for over a century — have always specialized in this kind of edible theater: things that are as fun to watch made as they are to eat. The candy's Squid Game revival sparked genuine global interest in Korean food and culture more broadly, alongside K-drama, K-pop, and Korean cinema. But there is something particularly poetic about dalgona: a two-ingredient candy made by elderly vendors on city sidewalks became the image that made the entire world stop and pay attention to Korean culture.
