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

What each ingredient does

Granulated sugar
Provides sweetness and body, and the scorched portion adds deep caramel flavor and color.
Milk
Adds moisture and creaminess, letting the sugar cook into a smooth, spreadable mixture.
Butter
Adds fat for richness and a softer, smoother texture in the finished icing.

The step that matters

Scorching the sugar. Sugar darkens quickly, and once it passes deep amber it turns bitter and acrid. Stop at the right color, because burnt sugar will spoil the flavor of the whole icing.
