Why it works: Clove and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 17,451 recipes. Both carry ethyl octanoate, which smells fruity, wine. The science ↓
Salmi of Duck
Ingredients
Directions
Make the stock
Put the bones and giblets in a saucepan and cover with hot water.
When it boils, add the sliced onion, cloves, herbs, pepper, and salt, then cover.
Cook slowly for 1 hour.
Strain the mixture, then cool it to remove any fat on top.
Cook the duck and thicken
Return the strained liquid to the heat and add the duck pieces.
Simmer for 1 hour, adding water if needed.
Brown the flour and butter together.
Stir the browned mixture into the duck mixture and let it boil.
Add stewed green peas just before thickening, if desired.
Serve
Arrange the duck on a platter.
Garnish with croutons or boiled rice.

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 rich flavour that the soup is built around.
- Bones and giblets
- Release gelatin and savoury flavour into the water, giving the stock body.
- Onion
- Adds aromatic sweetness and depth to the stock as it cooks slowly.
- Flour
- Thickens the soup when browned with butter and stirred in.
- Butter
- Carries the flour and adds richness while browning, adding nutty aroma.
The step that matters
Skimming the fat after straining. Fat left on the stock makes the soup greasy and can mute its flavour. Cooling the strained liquid lets the fat rise and solidify so it can be removed.
Swap the peas
The recipe marks peas as optional. How well each one fits the dish's main ingredients (onion, clove, pepper, flour, butter, rice):
- Black-eyed peafits better
- Chickpeafits better
- Beansfits better
- Peasthe original
Fit is the average pairing score against onion, clove, pepper, flour, butter, rice. Candidates are from the same food group and used in at least 100 recipes.
