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, cooked through by roasting.
Butter
Melts with flour to form a roux that thickens the sauce and adds richness.
Flour
Thickens the sauce when cooked with melted butter.
Orange juice
Adds bright acidity and sweetness that balance the rich duck.
Orange rind
Contributes aromatic oils and a bitter citrus flavour to the sauce.

The step that matters

Stir in the boiled rinds and bring the sauce to a boil. Rind must be pared thin and boiled first so its bitterness is mellowed and the shreds stay tender. Boiling the finished sauce thickens the flour mixture fully, so it reaches a smooth consistency without lumps.

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.
