December in Copenhagen is dark by three in the afternoon. The streets glow with candles in every window, and the cold follows you inside, settling into your coat, your hands, the tips of your ears. This is when varm chokolade matters most.

This is not a powdered drink. Not a sachet stirred into hot water. Danish hot chocolate starts with good dark chocolate, broken into pieces and melted slowly into whole milk until it thickens into something glossy and almost black. The cream goes in twice: once in the pot for body, once on top as flødeskum, the soft whipped cream that melts into the surface as you drink. Two ingredients doing two different jobs. That's the architecture of the cup.

Pay attention to one thing: the heat. Milk scorches easily, and scorched milk ruins everything it touches. Keep the flame low, stir often, and let the chocolate do its work at its own pace. You'll know when it's right because the surface turns glossy and the whisk leaves a trail that closes slowly behind it. Pour it into deep mugs, add the cream, and carry it to wherever the candles are lit. This is what hyggelig feels like when you're holding it in both hands.
