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 filling, becoming tender when cooked until easily penetrated with a fork.
Eggs (in the method)
Set into the structure of the omelet that holds the liver filling.
Butter
Fat for the pan that prevents the livers and eggs from sticking and burning.
Dark rich gravy or sauce espagnole
Adds savoury depth and moisture to the liver mixture.
Sherry
Adds aroma and a touch of sweetness and acidity to the liver mixture.

The step that matters

Cook the livers until easily penetrated with a fork. Overcooked liver becomes dry and grainy because proteins tighten and squeeze out moisture, while undercooked liver stays soft and unsafe. Testing with a fork shows when the centre is cooked through but still tender.

Swap the onion

How well each one fits the dish's main ingredients (chicken, liver, butter, vinegar, sauce, pepper, sherry):

  1. Capsicumfits better
  2. Mustardfits about as well
  3. Onionthe original
  4. Tomatofits about as well

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