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.
