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 when beaten with sugar gives the sauce its creamy body.
Powdered sugar
Adds sweetness and dissolves easily into the butter, helping the sauce stay smooth.
Egg whites
Beaten in, they add air that lightens the texture of the sauce.

The step that matters

Adding the egg whites one at a time. Adding them gradually lets each one emulsify fully into the butter-sugar mixture. Dumping them in together can cause the mixture to separate or look curdled, and beating until very light traps air for a fluffy texture.

Swap the nutmeg

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

  1. Cinnamonfits better
  2. Nutmegthe original
  3. Clovefits less well
  4. Allspicefits less well

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