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 ↓
Fricassee of Ducks
Ingredients
Directions
Prepare the duck
Clean, wash, and cut the ducks into four pieces each.
Flour the duck pieces and fry them in oil until light brown.
Drain the duck pieces and pour stock and claret into a saucepan.
Stew and make the gravy
Add chopped parsley, minced onion, salt, and pepper; cover and stew for 30 minutes until tender.
Remove the duck pieces, strain the gravy, and set it in cold water to separate the fat.
Remove the fat and thicken the gravy with browned flour mixed with water.
Serve
Boil the gravy, return the duck pieces to heat, and serve very hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ducks
- Provide the meat, which becomes tender through slow stewing in liquid.
- Flour
- Coats the duck so it browns in the frying oil and gives a crisp surface.
- Stock
- Forms the moist liquid base that cooks the duck and becomes the gravy.
- Claret
- Adds acidity and wine flavour to the gravy during stewing.
- Browned flour
- Thickens the gravy and adds a toasted, nutty colour and flavour.
The step that matters
Frying the floured duck until light brown. Browning the flour-coated surface builds colour and flavour through the Maillard reaction. Frying too hot can scorch the coating before the meat is cooked, while too little heat leaves it pale and greasy.
Swap the onion
How well each one fits the dish's main ingredients (flour, parsley, pepper):
- Carrotfits better
- Shallotfits better
- Parsnipfits better
- Onionthe original
Fit is the average pairing score against flour, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
