Why it works: Chicken and onion are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 17,814 recipes. Both carry gamma-nonanolactone, which smells coconut, sweet. The science ↓
Chicken Custards
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Make the custard
In a bowl, mix the chicken stock, onion juice, salt, and pepper.
Beat the eggs well and add to the mixture.
Pour the mixture into buttered custard cups.
Bake
Place the cups in a pan of hot water and bake until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken stock
- Provides the main liquid and savory flavor of the custard.
- Eggs
- Set during baking to give the custard its firm, tender structure.
- Onion juice
- Adds a mild savory aroma to the custard.
The step that matters
Bake in a pan of hot water until set. Eggs set into a delicate custard at moderate heat; baking the cups in hot water moderates the temperature around them, helping prevent a curdled, rubbery texture.
Swap the onion
How well each one fits the dish's main ingredients (chicken, egg, pepper):
- Capsicumfits better
- Asparagusfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against chicken, egg, pepper. 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.
