Why it works: Cocoa powder and sugar are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 2,920 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Cocoa
Ingredients
Directions
Heat the milk in a double boiler until scalded.
In a separate bowl, dissolve the cocoa, sugar, and salt in a little boiling water.
Stir the cocoa mixture into the hot milk.
Cook for 15 minutes, then beat with a whisk for 1 minute.
Serve immediately.
