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 ↓
Butter, Fairy
Ingredients
Directions
Make the paste
Beat the yolks of the eggs smoothly in a mortar with the orange-flower water and sugar until fine.
Press the butter
Add the butter and force it through a clean cloth by wringing and squeezing hard.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled egg yolks
- Add richness and body, helping bind the paste into a smooth mass.
- Good fresh butter
- Supplies fat for richness and a smooth, creamy texture.
- Powdered sugar
- Sweetens the paste and dissolves finely into the yolks for a smooth texture.
- Orange-flower water
- Adds a delicate floral aroma.
The step that matters
Forcing the butter through the cloth. Butter that is too warm softens and melts, so it separates from the yolk paste instead of forming a smooth, cohesive mass. Firm, evenly worked butter keeps the fat dispersed and the texture fine.
Swap the orange
How well each one fits the dish's main ingredients (egg, sugar, butter):
- Vanillafits better
- Lemonfits better
- Raisinfits better
- Orangethe original
Fit is the average pairing score against egg, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
