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

What each ingredient does

Ducks
Provide the main meat, which becomes tender during the long gentle boiling.
Flour
Dredging adds a light coating that helps the surface hold onto the dish's sauce.
Gravy
Adds savory liquid and body to the sauce that coats the ducks.
Onion
Adds aromatic flavor and sweetness to the sauce as it stews.
Butter
Adds fat and richness to the sauce, rounding out its flavor.

The step that matters

Boiling the ducks in cold water. Starting the ducks in cold water and bringing them up to a boil lets heat penetrate gradually, so the meat cooks through and becomes tender rather than tough on the outside.

Swap the onion

How well each one fits the dish's main ingredients (milk, flour, parsley, lemon, pepper, butter):

  1. Shallotfits better
  2. Carrotfits better
  3. Arrowrootfits better
  4. Onionthe original

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