Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and a creamy, smooth body to the sauce.
- Powdered sugar
- Provides sweetness and dissolves into the fat to give a smooth texture.
- Egg
- Adds moisture and helps emulsify the butter and sugar into a creamy blend.
The step that matters
Mixing until creamy. Butter must be soft enough to cream with the sugar. Sifting the sugar first removes lumps so the sauce comes out smooth rather than grainy. Cold butter won't blend evenly and leaves lumps in the finished sauce.
Swap the nutmeg
How well each one fits the dish's main ingredients (butter, sugar, egg):
- Cinnamonfits about as well
- Nutmegthe original
- Capersfits less well
- Parsleyfits less well
Fit is the average pairing score against butter, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
