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

What each ingredient does

Onion
Softened in butter to build a sweet, mild base for the sauce.
Butter
Fat that softens the onion and carries flavour into the sauce.
Flour
Thickens the boiling water into a smooth sauce that clings to the duck.
Duck
Cooked meat that provides the main substance and rich flavour of the hash.

The step that matters

Add the duck without boiling. Once the duck is in the sauce, boiling can toughen cooked meat and make it dry and stringy. Gentle heat only warms it through while keeping it tender.

Swap the onion

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

  1. Capsicumfits better
  2. Shallotfits better
  3. Turnipfits better
  4. Onionthe original

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