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

What each ingredient does

Butter
Provides fat that gives the sauce a rich, creamy body once softened and beaten.
Powdered sugar
Dissolves into the fat to add sweetness and a smooth, fine texture.

The step that matters

Beat the butter until well softened. Butter must be soft enough to cream properly. If it is too cold, the sugar will not blend in smoothly and the sauce stays lumpy. If it is too warm or melted, the sauce turns greasy and loses its body.

Swap the nutmeg

How well each one fits the dish's main ingredients (butter, sugar):

  1. Cinnamonfits better
  2. Nutmegthe original
  3. Gingerfits less well
  4. Capersfits less well

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