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

What each ingredient does

Duck
Provides the main protein and rich fat that renders during roasting.
Bread crumbs
Absorb juices from the cavity and add soft body to the stuffing.
Butter
Adds fat that carries aroma and gives the stuffing a rich, tender texture.
Onion
Releases sweetness and moisture as it softens inside the stuffing.
Sage
Contributes a savoury, herbal aroma that flavours the stuffing and meat.

The step that matters

Roast the duck until it is well done. Duck skin fat must render fully and the meat must cook through; stopping early leaves flabby skin and unsafe meat. Doneness should be checked with a thermometer rather than by colour alone.

Swap the onion

How well each one fits the dish's main ingredients (sage, bread, butter, pepper):

  1. Capsicumfits better

  4. Onionthe original

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