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
Dust the duck pieces with flour and fry them in a pan until light brown.
Drain the duck pieces and place them in a saucepan.
Stew
Add gravy, claret, chopped parsley, minced onion, salt, and pepper.
Cover the saucepan and stew for 30 minutes or until the ducks are tender.
Finish the gravy and serve
Remove the duck pieces and strain the gravy.
Set the gravy in cold water to separate the fat, then remove the fat.
Thicken the gravy with browned flour mixed with water, then bring to a boil.
Place the duck pieces on a flat dish and pour the gravy over them.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ducks
- Provide the meat that becomes tender during slow stewing in liquid.
- Flour
- Dusted on the duck and browned flour thickens the gravy, adding body and color.
- Claret
- Adds acidity and wine flavor that balances the richness of the duck and gravy.
- Gravy or soup stock
- Forms the cooking liquid that carries flavor and becomes the serving sauce.
- Onion
- Adds aromatic sweetness and savory depth to the stewing liquid.
The step that matters
Set the gravy in cold water to separate the fat. Fat rises and solidifies as the gravy cools, so chilling lets it be lifted off. Skipping this leaves the sauce greasy and heavy on the palate.
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.
