Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cornstarch
- Thickens the hot milk as its starch swells and sets the drink's body.
- Milk
- Forms the liquid base that carries the chocolate and gives the drink its creamy body.
- Sugar
- Adds sweetness that balances the bitterness of the unsweetened chocolate.
- Unsweetened chocolate
- Provides the main chocolate flavor and cocoa fat that makes the drink rich.
The step that matters
Adding the cornstarch mixture to the hot milk. Pour the cornstarch mixture in slowly while stirring constantly. Starch added too fast clumps instead of dispersing, and stirring keeps it evenly suspended so it thickens smoothly as the milk heats.
