Dalgona coffee originated as a street snack in South Korea, where dalgona candy (a caramel‑like sweet) is made by whisking sugar and baking soda. The coffee version became a viral TikTok trend in 2020, symbolizing the pandemic’s home‑cooking creativity and quickly spread worldwide.

In Korea, the basic recipe uses instant coffee, sugar, and hot water, but some cafés add a pinch of salt, cocoa powder, or matcha for color and flavor. In other regions, people sometimes replace the milk base with sweetened condensed milk for extra richness.

It is traditionally served in a clear glass over a generous amount of cold milk, allowing the fluffy coffee foam to sit on top like a cloud. The drink is stirred before drinking to blend the creamy foam with the milk.

While not tied to a specific holiday, Dalgona coffee is popular during gatherings, study sessions, and as a refreshing treat in the hot summer months. Its eye‑catching appearance also makes it a favorite for social‑media sharing at parties.

Dalgona coffee pairs nicely with traditional Korean teas such as barley tea (bori‑cha) or sweet rice punch (sikhye) for a balanced flavor contrast. It also complements Korean dessert pastries like hotteok or bingsu.

Its uniqueness lies in the simple chemical reaction that turns instant coffee, sugar, and hot water into a light, airy foam resembling whipped cream, creating a striking visual and textural contrast with the milk beneath.

Common errors include using cold water, which prevents the sugar from dissolving; whisking for too short a time, resulting in a runny mixture; and using too much or too little sugar, which affects sweetness and stability.

Instant coffee contains fine particles and soluble solids that create a stable foam when combined with sugar and hot water, whereas brewed coffee lacks the necessary texture and will not whip into peaks.

Yes, you can whisk the foam ahead and keep it in an airtight container in the refrigerator for up to 24 hours. Before serving, give it a quick re‑whisk to restore some of the airy texture, then spoon onto cold milk.
