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 ↓

Ingredients
Directions
Prepare the custards
Mix the yolks of four eggs with a little water and a pinch of salt.
Strain the mixture and divide it into three equal portions.
Color one portion with cochineal, one with spinach greening, and leave the third plain.
Steam and finish
Pour each mixture into three buttered moulds and dip them into a pan of hot water.
Steam just long enough to set the custards.
Remove from heat and let cool before turning out onto a napkin.
Cut into dice or pretty shapes with a vegetable cutter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Set into a firm, smooth custard when gently heated, giving the royale its structure.
- Water
- Thins the yolks so the custard sets soft and smooth rather than dense.
The step that matters
Steam just long enough to set the custards. Egg proteins set with gentle heat, and too much heat or time makes the custard curdle, weep and turn spongy or grainy. Stop as soon as it is set.
Swap the spinach
How well each one fits the dish's main ingredients (egg, butter):
- Asparagusfits better
- Chivefits better
- Leekfits better
- Spinachthe original
Fit is the average pairing score against egg, butter. Candidates are from the same food group and used in at least 100 recipes.
