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

What each ingredient does

Butter
Adds richness and a smooth, creamy body to the sauce.
Sugar
Sweetens the sauce and helps it become creamy when beaten with the butter.
Egg whites
Whipped in to lighten the texture and make the sauce fluffy.
Brandy
Adds a warm, aromatic alcohol flavor that complements the sweetness.

The step that matters

Beating the butter and sugar until creamy. Beating incorporates air into the butter while the sugar crystals cut into it, creating a light, smooth base. If the butter is too cold or the beating is too short, the mixture stays grainy and dense, and the egg whites will not blend in evenly.

Swap the nutmeg

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

  1. Cinnamonfits about as well
  2. Nutmegthe original
  3. Clovefits less well
  4. Gingerfits less well

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