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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken
- Provides the main protein, which browns in lard to build savory flavor before simmering.
- Flour
- Thickens the cooking liquid into a smooth sauce as it is stirred into the fat.
- Egg yolk
- Enriches the sauce, adding body and richness when mixed in at the end.
- Lard
- Adds fat for browning the chicken and carrying flavor through the dish.
- Vinegar
- Adds acidity that brightens the rich sauce.
The step that matters
Mix in the egg yolk off the heat. Egg yolk thickens by gentle heat and can scramble or curdle if the sauce is too hot. Straining first and adding it at a low temperature keeps the sauce smooth and glossy.
Swap the onion
How well each one fits the dish's main ingredients (chicken, flour, vinegar, sherry, sauce, pepper, egg):
