Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh butter
- Forms the rich base that gives the dish its smooth, creamy body.
- Hard-boiled egg yolks
- Add richness and help bind the butter into a smooth, thick mixture.
- Sweet almonds
- Add body and a nutty flavor when pounded into a paste.
- Pounded loaf sugar
- Sweetens the mixture so it balances the richness of the butter and yolks.
- Naples biscuits
- Soak up the white wine and provide a crisp, absorbent base for the butter.
The step that matters
Work the mixture through an earthenware colander. Pressing the mixture through a sieve breaks up lumps and fibres, giving a smooth, even texture. Skipping this step leaves the butter grainy and uneven.
Swap the orange
How well each one fits the dish's main ingredients (butter, egg, almond, lemon, sugar, biscuit, white wine):
- Vanillafits better
- Figfits about as well
