Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Roast Chickens
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the stuffing
Clean and wash the chickens in several waters.
Mix bread crumbs with tepid water, drain, and heat in a saucepan with hot butter until hot and almost dry.
Add chopped parsley, salt, and pepper to the crumbs, then remove from heat and beat in the frothed eggs.
Stuff the chickens with the mixture, sew up the vents, and tie the necks.
Roast and baste
Cover the breasts with greasy writing paper.
Place a cup of boiling water in the dripping pan and roast the chickens at 400°F (200°C) for one hour, basting frequently.
Ten minutes before finishing, remove the paper and baste the breasts three times with butter until browned.
Make the gravy and serve
Pour off the fat from the gravy, add chopped egg yolks, browned flour, pepper, and salt, then boil and serve in a boat.
Salt the giblets slightly and keep on ice for tomorrow's soup.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chickens
- Provide the main body that the stuffing fills and the roasting cooks through.
- Bread crumbs
- Absorb the butter and moisture, forming a dry, binding stuffing that holds its shape.
- Eggs
- Bind the stuffing as they set with heat, giving it a firmer texture.
- Butter
- Adds richness and helps the breasts brown during the final basting.
- Egg yolks
- Enrich and thicken the gravy as they cook, giving it body and colour.
- Browned flour
- Thickens the gravy and adds a toasted, nutty flavour and colour.
The step that matters
Ten minutes before finishing, remove the paper and baste the breasts with butter. Removing the greased paper lets the breast skin brown, and the timing matters: leaving the paper on too long keeps the skin pale, while removing it too early can dry the breast before the bird is cooked through.
Swap the parsley
How well each one fits the dish's main ingredients (chicken, bread, butter, pepper, egg, flour):
- Parsleythe original
- Nutmegfits about as well
- Capersfits less well
- Tarragonfits less well
Fit is the average pairing score against chicken, bread, butter, pepper, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
