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

What each ingredient does

Sugar
Dissolves into the milk and sets into a sweet, firm frosting as it cooks and cools.
Milk
Provides the liquid that dissolves the sugar and carries it to the boil for a creamy texture.
Butter
Adds richness and a smoother mouthfeel to the frosting.

The step that matters

Boil without stirring for 12 minutes. Stirring during the boil can cause sugar crystals to form, leaving the frosting grainy. Keeping the pan still lets the syrup reach the right concentration so it thickens smoothly when beaten.
