Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Provides richness and a smooth, firm body once creamed with sugar.
- Egg white
- Whipped to stiff peaks, it lightens the sauce and adds airy structure.
- Powdered sugar
- Dissolves easily into the butter, sweetening and smoothing the texture.
The step that matters
Fold the egg white into the butter mixture. Folding gently keeps the whipped egg white's air trapped. Stirring or overmixing deflates it, leaving a dense, heavy sauce instead of a light one.
Swap the nutmeg
How well each one fits the dish's main ingredients (butter, egg, sugar):
- Cinnamonfits about as well
- Nutmegthe original
- Capersfits less well
- Parsleyfits less well
Fit is the average pairing score against butter, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
