Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown sugar
- Provides sweetness and caramel flavor as it cooks down with the milk.
- Butter
- Adds fat for a smooth, rich texture in the icing.
- Sweet milk
- Supplies liquid that dissolves the sugar and thickens as it cooks.
- Chocolate
- Adds chocolate flavor and deepens the colour of the icing.
The step that matters
Cooking until smooth and thick. Heating sugar and milk together thickens the mixture as water evaporates and sugars concentrate. Undercooked icing stays runny and may not set, while overcooking can make it grainy or stiff once cooled.
