Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Icing sugar
- Sweetens the icing and gives it a soft, fine body as it is beaten.
- Fresh butter
- Provides fat that makes the icing rich and creamy when beaten.
- Powdered chocolate
- Supplies the chocolate flavour and adds solids that give the icing body.
- Brandy or liquor
- Adds liquid to loosen the mixture and contributes aroma.
The step that matters
Mix with a wooden spoon for about 15 minutes until creamy. Beating incorporates air and fully blends the fat with the sugar and chocolate. Stopping early can leave a grainy or dense icing, while the butter needs to be soft enough to cream smoothly.
