Why it works: Celery and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Fricassee of Chicken a LA Reine
Ingredients
Directions
Poach the chicken
Place the jointed chickens in a large saucepan with 1 quart of cold water.
Bring the mixture to a slow boil.
Add celery, parsley, bay leaf, onion, salt, and pepper to the pot.
Cover and simmer for 30 minutes.
Test the chicken with a fork to check doneness.
Remove the chicken from the gravy and keep it warm over hot water.
Make the sauce
In a separate saucepan, cook butter and flour together until bubbling, without browning.
Slowly add the strained chicken gravy to the butter‑flour mixture, stirring constantly, and let it boil for 2 minutes.
In a bowl, mix egg yolks, milk, melted butter, and red pepper.
Carefully add the egg mixture to the hot sauce, stirring continuously without boiling.
Add lemon juice to the sauce.
Serve
Pour the sauce over the chicken and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chickens
- Provide the meat that is poached and then served in the sauce.
- Butter and flour
- Form a roux that thickens the gravy into a smooth sauce.
- Chicken gravy
- Forms the liquid base of the sauce, carrying the chicken flavor.
- Egg yolks
- Enrich the sauce and thicken it gently when heated.
- Milk
- Adds moisture and softens the richness of the egg yolk mixture.
- Lemon juice
- Adds acidity that brightens the rich, creamy sauce.
The step that matters
Adding the egg mixture to the hot sauce. Egg yolks thicken when heated gently but scramble if the sauce boils. Adding them slowly while stirring constantly, and keeping the sauce below a boil, keeps the sauce smooth.
