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 custard
Mix the yolks of 4 eggs with ½ cup of broth and a pinch of salt.
Strain the mixture and divide it into 3 equal portions.
Color one portion with cochineal, one with spinach‑greening, and leave the third plain.
Poach and set
Pour each mixture into buttered moulds and dip them one-third deep into hot water.
Cover and poach until the custards are set.
Remove from heat, let cool, and turn out onto a napkin.
Serve
Cut into dice or shapes with a vegetable cutter and add to the soup just before serving.

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, tender custard when gently heated, giving the garnish its structure.
- Broth
- Thins the yolks so the custard sets smooth and moist rather than dense.
The step that matters
Poach and set. Heat must stay gentle, with the moulds dipped only partway in hot water. Egg proteins set firmly at moderate temperatures, and boiling or too-high heat makes the custard curdle, pockmarked, or rubbery.
Swap the spinach
The recipe marks spinach as optional. 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.
