Hot chocolate made on aguapanela rather than milk or water, whisked until it foams. Two ways: with chocolate tablets or with instant chocolate. Five minutes either way.
Aguapanela is the base and the reason this tastes different from hot chocolate anywhere else: panela dissolved in hot water, unrefined and faintly smoky, doing the job that milk or water does elsewhere. The foam is not decoration either. Whisking hard off the heat is what emulsifies the cocoa fat into the liquid, and a Colombian cup is judged partly on how much foam sits on top. A molinillo, the carved wooden whisk rolled between the palms, is the traditional tool, and an ordinary hand whisk gets you there. And in much of Colombia a chunk of fresh cheese goes into the cup, where it softens and is eaten with a spoon at the end.
