Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks add richness and thicken the drink as they warm.
- Sugar
- Sweetens the drink and helps the yolks whip into a light, foamy base.
- Unsweetened cocoa powder
- Provides the chocolate flavor and color.
- Boiling water
- Dissolves the cocoa and forms the liquid body of the drink.
The step that matters
Pouring the hot mixture over the eggs while stirring briskly. Stirring spreads the heat quickly so the yolks warm gradually. If hot liquid hits the yolks in one spot, they can scramble and curdle instead of thickening smoothly.
