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

What each ingredient does

Flour
Thickens the sauce, giving it body as it cooks with the butter.
Butter
Adds fat and richness to the onion and the thickened sauce.
Onion
Adds savory flavor and body to the sauce as it softens without browning.

The step that matters

Do not let it boil. Once the sauce is thickened and the duck is added, boiling can toughen the meat and cause the flour-thickened sauce to break or become uneven. Gentle heat keeps the texture smooth and the meat tender.

Swap the onion

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

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

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