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 savory body and meaty texture of the filling.
Cream
Adds moisture and richness, forming the creamy base that holds the filling together.
Flour
Thickens the cream as its starch swells with heat, giving the filling body.
Butter
Adds fat for rich flavor and helps carry the seasonings through the filling.
Hard boiled eggs
Add soft, firm bits of texture and a mellow richness to the filling.
Cooked rice
Adds bulk and a soft, tender texture that stretches the filling.

The step that matters

Cooking the livers for five minutes. Chicken livers turn dry and grainy if overcooked, because their proteins tighten under prolonged heat. Stirring keeps them cooking evenly and the sauce smooth.

Swap the nutmeg

How well each one fits the dish's main ingredients (chicken, liver, flour, cream, rice, egg, pepper):

  1. Turmericfits about as well
  2. Nutmegthe original
  3. Parsleyfits about as well
  4. Celeryfits less well

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