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

What each ingredient does

Butter
Provides fat that makes the sauce rich and creamy, and firms up when chilled.
Powdered sugar
Adds sweetness and dissolves smoothly into the butter for a fine, smooth texture.
Wine
Adds liquid and fruity flavor that balances the richness of the butter.
Lemon juice
Adds acidity that brightens the sweetness and cuts through the butter.
Grated nutmeg
Adds warm aromatic spice that gives the sauce its characteristic flavor.

The step that matters

Place the mixture on ice to harden. Butter is solid when cold and soft when warm, so the sauce only sets firm once it is thoroughly chilled. If it stays warm, it will remain loose and spreadable rather than holding its shape.

Swap the nutmeg

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

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

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