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

What each ingredient does

Chicken livers
Provide the main protein, cooking through to a tender texture in the skillet.
Butter
Adds fat and richness, and carries the onion flavor into the sauce.
Flour
Thickens the pan liquid into a smooth sauce as it whisks in.
Onion
Builds sweet, savory aroma as it softens in the butter.
Hot water or stock
Forms the liquid base of the sauce and lifts browned bits from the pan.

The step that matters

Whisk in the flour. Flour added to liquid can clump if not whisked in smoothly, leaving lumps. Whisking it into the hot liquid disperses the starch so it thickens evenly as the sauce heats.

Swap the onion

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

  1. Shallotfits better
  2. Carrotfits better
  3. Potatofits about as well
  4. Onionthe original

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