Why it works: Egg and butter are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 118,967 recipes. Both carry decanal, which smells soap, orange peel. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Provide richness and a smooth, creamy body to the butter.
- Butter
- Adds fat for a rich, spreadable texture and mild flavor.
- Powdered sugar
- Adds sweetness and dissolves smoothly into the mixture.
- Orange flower water
- Adds a light floral aroma.
The step that matters
Chill, then rub through a sieve. The mixture must be cold so the butter is firm enough to hold its shape and pass through the sieve smoothly. Warm butter stays soft and can clog the sieve or turn greasy.
Swap the orange
How well each one fits the dish's main ingredients (egg, butter, sugar):
- Vanillafits better
- Lemonfits better
- Raisinfits better
- Orangethe original
Fit is the average pairing score against egg, butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
