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
Make the custard
Mix the yolks of six eggs with ⅓ cup cold water and a pinch of salt.
Strain the mixture.
Divide the strained mixture into three equal parts.
Color one part with cochineal.
Color another part with spinach greening.
Leave the third part plain.
Set the custard
Butter three moulds.
Fill the moulds with the colored mixtures.
Place the moulds in a pan of hot water.
Boil the moulds just long enough to set the mixture.
Once set, cool the moulds.
Turn out the custard onto a wet napkin.
Cut and serve
Cut the custard into small dice.
Spread the dice on a plate, covering until ready to use.
Add the custard pieces to the soup tureen with the consommé.

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 custard when gently heated, giving the garnish its structure.
- Cold water
- Thins the yolks so the custard stays tender rather than rubbery.
The step that matters
Boil the moulds just long enough to set the mixture. Egg custard turns grainy and spongy if overheated, because the proteins tighten too far and squeeze out water. Stop once the custard has just 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.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
