Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Provides liquid that dissolves the sugar and melts the chocolate into a smooth icing.
- Grated chocolate
- Supplies the chocolate flavour and, as it melts, thickens the icing.
- Egg white
- Adds protein that sets and thickens the icing as it heats.
- Sugar
- Adds sweetness and helps give the icing body as it cooks.
The step that matters
Cook over medium heat while stirring constantly. Egg white can scramble or stick to the pan if heated unevenly or left unstirred. Constant stirring keeps the mixture smooth and lets it thicken evenly.
