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, giving the sauce a smooth, creamy body.
Powdered sugar
Sweetens the sauce and dissolves smoothly into the butter for a fine texture.
Lemon juice
Adds acidity that brightens the sweetness and balances the rich butter.
Wine or brandy
Adds alcohol-based aroma and depth of flavour that the sauce would otherwise lack.

The step that matters

Creaming the butter and powdered sugar until smooth. Butter softened and beaten with sugar traps air and dissolves the sugar grains, so the sauce turns smooth rather than gritty. Rushing this step leaves a grainy texture.

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.
