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

What each ingredient does

Brown sugar
Provides caramel flavor and sweetness, and helps give the frosting its color.
Powdered sugar
Adds sweetness and body, helping the frosting set firmer as it cools and thickens.
Milk
Adds moisture so the sugars dissolve and the mixture can be boiled into a spreadable frosting.
Butter
Adds fat for smoothness and richness, giving the frosting a softer, creamier texture.
Baker's chocolate
Adds chocolate flavor, depth, and color to the frosting.

The step that matters

Boiling until the butter shreds. Boiling sugar and milk to the right point controls how the frosting sets. Too little boiling leaves it soft and runny, while too much makes it stiff and grainy. Beating while it cools lets the sugar crystallize into a smooth, thick texture.

Swap the lemon

Fit is the average pairing score against sugar, milk, butter, chocolate, vanilla. Candidates are from the same food group and used in at least 100 recipes.
