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 ↓
Stewed Duck and Peas
Ingredients
Directions
Make the stew
Melt the butter and add the bacon, then cook over medium heat until lightly browned.
Stir in the flour, then add the broth or water and mix gently until boiling.
Skim the surface.
Add the onions, parsley, bay leaf, and cloves, and simmer for 15 minutes.
Add the peas and continue to simmer for about 30 minutes until done.
Finish and serve
Remove the duck and place it on a serving dish, then discard the trussing string.
Remove the parsley and bay leaf from the stew.
Season the peas with pepper, salt, and sugar.
Skim off excess fat.
Reduce the sauce if it's not thick enough.
Pour the sauce over the duck.
Serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Duck
- Forms the main body of the dish, releasing fat and juices that flavour the stew.
- Butter
- Carries the bacon's flavour and enriches the sauce with fat.
- Flour
- Thickens the broth into a sauce as it cooks.
- Bacon
- Browns in the fat to add savoury, smoky depth to the stew.
- Young peas
- Add sweetness and a tender texture as they simmer in the sauce.
- Button onions
- Soften during simmering and add mild sweetness to the sauce.
The step that matters
Reduce the sauce if it's not thick enough. Flour thickens the broth only as it simmers and reduces. Cooking too briefly leaves a thin sauce, while over-reducing can make it overly salty and dense, so check consistency gradually.
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.
