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 forms the creamy body of the icing.
- Sugar
- Sweetens the icing and, as it cooks, thickens the mixture into a caramel-like texture.
- Butter
- Adds fat for smoothness and a rich mouthfeel in the finished icing.
- Chocolate
- Supplies the chocolate flavour and fat that set the icing as it cools.
The step that matters
Boil until it thickens. Stirring constantly keeps the sugar and milk from scorching on the bottom of the pan. Stop the boil too early and the icing stays thin; cook too long and it turns stiff and grainy as it cools.
