Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chocolate
- Provides the main flavour and body of the drink as it melts into the liquid.
- Milk
- Adds creaminess and a softer, rounder texture to the drink.
The step that matters
Stirring while the milk boils. Milk proteins and sugars can scorch and stick to the bottom of the pan when heated for a long time. Stirring often spreads the heat evenly and keeps the milk from catching or forming a skin on top.
