Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Milk
Forms the liquid base and gives the drink its creamy body.
Sugar
Adds sweetness and balances the bitterness of the chocolate.
Chocolate
Provides the main flavor and cocoa fat that adds richness.
Egg
Its proteins set when heated, thickening the drink and adding body.

The step that matters

Adding the egg-chocolate mixture to the milk. Egg proteins set when heated, so pouring the mixture into very hot milk too quickly can cause it to curdle or turn grainy. Stirring steadily while adding it keeps the egg evenly dispersed and the drink smooth.
