Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Chicken En Fricassee
Ingredients
Directions
Make the sauce
In a large saucepan, melt the butter over medium heat.
Mix in the flour until smooth, then add enough hot water to cover half of the chicken.
Cook the chicken
Bring the sauce to a boil, then add the chicken, neck, and head, along with bay leaves and lemon peel.
Cover and simmer for 30 minutes, turning the chicken halfway through.
Add the small onions and cook until the chicken is done.
If the sauce is too thin, remove the chicken and onions, and let the sauce reduce by boiling.
Finish and serve
Before serving, slowly stir the sauce into the beaten egg yolk.
Serve the chicken with the sauce poured over it, adding mushrooms if desired.

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; slow simmering in liquid keeps the meat tender and moist.
- All-purpose flour
- Thickens the sauce as it cooks with the butter and liquid.
- Butter
- Adds richness and flavor to the sauce and helps form the flour base.
- Egg yolk
- Enriches and thickens the finished sauce, giving it a smoother, creamier body.
- Small onions
- Become tender and sweet as they simmer in the sauce.
The step that matters
Stirring the sauce into the egg yolk. Adding hot sauce to the egg yolk too quickly can scramble it. Adding the sauce slowly, while stirring, gently warms the yolk so it thickens the sauce smoothly.
Swap the onion
How well each one fits the dish's main ingredients (chicken, butter, flour, lemon, egg, pepper, mushroom):
- Asparagusfits better
- Shallotfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against chicken, butter, flour, lemon, egg, pepper, mushroom. Candidates are from the same food group and used in at least 100 recipes.
