Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Wild ducks
Provide the main meat, which is cooked by roasting.
Oranges
Supply juice and rind that add acidity and bright citrus aroma to the sauce.
Butter
Adds richness and fat to the sauce and carries flavour.
Flour
Thickens the stock and butter into a smooth sauce.
Marsala
Adds wine-based sweetness and depth of flavour to the sauce.

The step that matters

Stir the sauce until it boils after adding the flour and stock. Flour must be cooked in hot butter and liquid to thicken fully and lose its raw taste. Stirring keeps it smooth and prevents lumps from forming as the starch swells.

Swap the orange

How well each one fits the dish's main ingredients (butter, flour, pepper, sugar, vinegar):

  1. Lemonfits better
  2. Figfits better
  3. Raisinfits better
  4. Orangethe original

Fit is the average pairing score against butter, flour, pepper, sugar, vinegar. Candidates are from the same food group and used in at least 100 recipes.
