Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Sugar
Sweetens the icing and helps it set firm as it cools and thickens.
Butter
Adds fat for a smooth, rich texture and a glossy finish.
Milk
Provides liquid that dissolves the sugar and cooks into a creamy base.
Grated chocolate
Supplies the chocolate flavor and color of the icing.

The step that matters

Beating while cooling. Beating the hot mixture in cold water cools it while sugar crystallizes, so it thickens into a spreadable texture. Stopping too early leaves it runny, while waiting too long can make it stiff and grainy.
