Ingredients
Directions

Stuff the chicken with bread crumbs seasoned with pepper, salt, and thyme.
Tie a buttered paper around the chicken.
Place the chicken in a kettle of warm water and cover closely.

In a saucepan, combine 1 cup of the chicken liquid with butter and flour to thicken.
Add the beaten eggs and boil for one minute.
Stir in the chopped parsley and season to taste.
Place the yolks of the hard-boiled eggs in a bowl.
Pour the sauce over them and stir.

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 and, cooked gently in water, becomes tender and juicy.
- Bread crumbs
- Absorb juices inside the cavity and add moisture and body to the stuffing.
- Butter
- Adds richness and a smooth, rounded flavour to the sauce.
- All-purpose flour
- Thickens the cooking liquid into a smooth, pourable sauce.
- Eggs
- Beaten eggs set into the sauce, giving it body and a creamy texture.
- Hard-boiled eggs
- Their yolks are mashed with the sauce, adding richness and a thick, custardy texture.
The step that matters
Adding the beaten eggs to the sauce. Eggs set when heated, so the sauce must be hot enough to cook them smoothly; boiling them for one minute ensures they thicken rather than curdle or stay runny.
Swap the thyme
How well each one fits the dish's main ingredients (chicken, bread, pepper, butter, flour, egg, parsley):

Fit is the average pairing score against chicken, bread, pepper, butter, flour, egg, parsley. Candidates are from the same food group and used in at least 100 recipes.
