How to Prepare Your CoffeeKorean Dalgona Coffee
Dalgona coffee is the froth that took over the internet from Korean kitchens: instant coffee, sugar, and hot water whipped into a stiff, caramel-coloured mousse and spooned over cold milk. There is no machine and no barista — just three equal parts and a whisk, worked until the mixture turns from syrup to cloud. The name comes from dalgona, the honeycomb candy that looks exactly like the whipped foam. It is a drink of lockdown mornings and quick indulgence, proof that instant coffee, treated with intent, can still surprise you.

Steps
Whip the instant coffee, sugar, and hot water into a stiff mousse
The magic is the 1:1:1 ratio. Equal parts coffee, sugar, and hot water whip together into a stable, dalgona-dark foam — the sugar dissolves, the instant granules release their solubles, and the mixture aerates into a mousse that holds its shape.
Spoon the foam over a glass of cold milk
The contrast is the drink: a dense coffee cloud floating on plain cold milk, waiting to be stirred in.
Stir it through and drink
Stirring dissolves the foam into the milk into a smooth, sweet coffee — the presentation is the pause, and the stir is the payoff.
Tips
- A hand mixer saves your arm — five minutes of whisking by hand builds the same foam in under two, and the result is identical.
- Use instant coffee, not brewed espresso; the granulated solubles are what whip into the stable dalgona mousse.
Common mistakes
- Under-whipping — stopping while the mixture is still runny gives you sweet coffee syrup instead of a mousse; whip until it holds a stiff peak and clings to the whisk.
- Adding cold water instead of hot — the heat is what dissolves the sugar and coffee into a whip-able base; cold water leaves you with a grainy slurry that will never aerate.
FAQ
What's the connection to dalgona candy?
The whipped foam is named after dalgona, the Korean honeycomb candy — a sweet, amber disc of melted sugar and baking soda pressed with a shape. The froth's caramel colour and honeycomb texture look so much like the candy that the coffee took its name.
