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

What each ingredient does

Butter
Creaming with sugar traps air and gives the sauce a soft, smooth, rich body.
Sugar
Sweetens the sauce and, creamed with butter, helps build its light, spreadable texture.
Lemon
Adds acidity and bright aroma from the juice and rind, balancing the sweetness.

The step that matters

Creaming the butter and sugar. Beating softened butter with sugar traps air in the fat, which gives the sauce its light texture. Cold or melted butter will not hold that air, so the sauce turns dense or greasy.

Swap the nutmeg

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

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

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