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 ‘capillotade’
Ingredients
Directions
Prepare the chicken
Remove the skin and bones from the chicken and cut it into pieces.
In a stewpan, moisten the chicken pieces with melted glaze and keep warm without boiling.
Make the onion sauce
Mince the onions and sauté them in butter over low heat until they take on color.
Add vinegar to the onions and let it reduce to a glaze.
Sprinkle flour over the onions and moisten with gravy or broth, then add pepper.
Combine and serve
Pour the onion mixture over the chicken and warm without boiling.
Sprinkle with chopped gherkins and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken
- Provides the main meat, which stays tender and moist when warmed gently rather than boiled.
- White onions
- Slow sautéing in butter browns their natural sugars, adding sweetness and savory depth.
- Butter
- Fat for sautéing the onions, carrying flavor and adding richness.
- Vinegar
- Adds acidity, and reducing it to a glaze concentrates its sharp tang.
- Gravy or broth
- Liquid that moistens the onions and forms the sauce around the chicken.
The step that matters
Warm without boiling. Boiling the chicken or the onion sauce toughens the meat and can break the sauce. Gentle heat keeps the chicken tender and moist while it warms through.
Swap the onion
How well each one fits the dish's main ingredients (chicken, butter, vinegar, pepper):
- Capsicumfits better
- Onionthe original
- Potatofits about as well
- Mustardfits about as well
Fit is the average pairing score against chicken, butter, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
