Why it works: Butter and nutmeg are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 24,377 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Provides the fat and body that firm up as the sauce chills.
- Powdered sugar
- Sweetens the sauce and, beaten in gradually, helps it become smooth and light.
- Flavoring
- Gives the sauce its main aroma and taste.
The step that matters
Adding the powdered sugar gradually. Adding sugar slowly while beating lets it dissolve evenly into the fat. Dumping it in at once can leave lumps and a grainy, dense texture.
Swap the nutmeg
The recipe marks nutmeg as optional. How well each one fits the dish's main ingredients (butter, sugar):
- Cinnamonfits better
- Nutmegthe original
- Gingerfits less well
- Capersfits less well
Fit is the average pairing score against butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
