Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown sugar
- Adds sweetness and caramel flavor, and moisture that keeps the icing soft.
- White sugar
- Adds sweetness and helps the mixture set smoothly as it cools.
- Milk
- Provides liquid that dissolves the sugars and gives the icing a creamy texture.
- Butter
- Adds fat for richness and a smooth, glossy texture.
- Baker's chocolate
- Adds chocolate flavor and deepens the color of the icing.
The step that matters
Boil the mixture for nine minutes, stirring occasionally. Boiling concentrates the sugar so the icing will set when cooled. Stirring prevents the sugar and milk from scorching on the bottom of the pan, which would give a burnt taste.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
