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

What each ingredient does

Butter
Creates the rich, creamy body of the sauce and carries flavor.
Sugar
Sweetens the sauce and, when beaten with butter, helps it turn light and creamy.

The step that matters

Beating the butter and sugar until creamy. Beating the butter and sugar together traps air and blends them into a smooth, spreadable texture. Under-beating leaves a grainy sauce, while adding liquid such as lemon juice or brandy too freely can thin it so it no longer holds its shape.

Swap the nutmeg

The recipe marks nutmeg as optional. How well each one fits the dish's main ingredients (butter, sugar, lemon, brandy):

  1. Cinnamonfits better
  2. Nutmegthe original
  3. Gingerfits less well
  4. Parsleyfits less well

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