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

What each ingredient does

Butter
Creamed to form the smooth base that carries the sugar and flavor.
Sugar
Beaten into the butter to add sweetness and a light, white, fluffy texture.

The step that matters

Keep on ice until very hard. Butter firms as it cools, so the sauce sets firm enough to hold its shape. Chilling too briefly leaves it soft and greasy, while the sugar keeps it from setting as hard as pure butter would.

Swap the nutmeg

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

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

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