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, which is cooked by roasting before a fire.
- Oranges
- Supply bright acidity and juice that lightly flavour the salad.
- Vinegar
- Adds sharp acidity that balances the sweetness of the oranges and sugar.
- Salad oil
- Adds fat that carries flavour and gives the dressing a smooth mouthfeel.

Fit is the average pairing score against orange, tarragon, vinegar, sugar, port wine, sauce. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
