Dalgona coffee became a viral sensation during the 2020 pandemic, but its roots trace back to a Korean street candy called dalgona, a honey‑comb‑like toffee. The coffee foam mimics the light, airy texture of that candy, turning a simple instant coffee into a trendy, Instagram‑ready drink.

While the classic version uses only instant coffee, sugar, and water, some Korean cafés add a splash of milk or flavored syrups, and others sprinkle cocoa powder or cinnamon on top for extra aroma. The basic technique, however, remains the same across regions.

In Korea, the whipped coffee foam is usually spooned over a glass of cold milk (or plant‑based milk) and served with a straw, allowing the drinker to stir the foam into the milk before sipping.

Dalgona coffee surged in popularity during lockdowns and is now a staple for casual brunches, TikTok challenges, and coffee‑shop social media posts, symbolizing a fun, easy‑to‑make treat.

The hallmark of Dalgona coffee is its thick, cloud‑like foam created by aerating instant coffee, sugar, and water. This texture contrasts with the smoothness of regular iced coffee and provides a visual and tactile novelty.

Common errors include using cold water (which prevents the sugar from dissolving), whisking for too short a time, and using a plate without a lip that lets the foam spill. Whisk until stiff peaks form and keep the plate stable.

The fine mesh strainer adds resistance, forcing the whisker to work harder and incorporate more air, which speeds up the formation of the fluffy foam compared to a regular whisk.

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 whisk to revive the airy texture.

The foam should be light, glossy, and hold stiff peaks—when you lift the whisk, the foam should form a mound that doesn’t collapse immediately and has a velvety, cloud‑like surface.

When the mixture changes from a watery brown liquid to a thick, pale‑beige foam that can hold its shape on the plate and forms stiff peaks, it is done. A quick test is to flip the plate; the foam should stay in place.
