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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Duck
- Provides the main meat and rendered fat that gives the stew its rich flavor.
- Butter
- Carries the bacon's flavor and helps it brown in the pan.
- Bacon
- Adds smoky, savory fat that builds the base flavor of the stew.
- Flour
- Thickens the broth into a body-rich sauce that clings to the duck.
- Button onions
- Soften during simmering and add sweetness and aroma to the sauce.
- Young peas
- Add sweetness and a tender texture to the finished stew.
The step that matters
Skim fat and reduce the sauce. Fat rises to the surface and can make the sauce greasy, so skimming removes it. Simmering evaporates water and concentrates the flour-thickened liquid, so the sauce coats the duck instead of running thin.
Swap the peas
How well each one fits the dish's main ingredients (butter, flour, onion, parsley, clove, pepper, sugar):
- Chickpeafits better
- Chestnutfits better
- Black-eyed peafits better
- Peasthe original
Fit is the average pairing score against butter, flour, onion, parsley, clove, pepper, sugar. Candidates are from the same food group and used in at least 100 recipes.
