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

What each ingredient does

Butter
Provides fat and richness, and creaming it with sugar gives the sauce a smooth body.
Powdered sugar
Sweetens the sauce and, dissolved into the butter, thickens it into a spreadable texture.
Lemon juice
Adds acidity that brightens the sweetness and balances the rich butter.
Wine or brandy
Adds alcohol-based aroma and flavor, and thins the sauce slightly.

The step that matters

Creaming the butter and sugar until smooth. Beating softened butter with powdered sugar incorporates air and dissolves the sugar into the fat, producing a smooth, light texture. Cold or unsoftened butter stays lumpy and the sauce turns out grainy.

Swap the nutmeg

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

  1. Cinnamonfits better
  2. Thymefits better
  3. Tarragonfits about as well
  4. Nutmegthe original

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