Chicken-Liver Omelet

Ingredients

Directions

Prepare the livers

  1. Remove the gall pouch from the chicken livers without breaking them.

  2. Wash the livers in cold water and parboil slightly; quarter if too large.

Make the sauce

  1. In a frying pan, melt enough butter to prevent burning and add the livers.

  2. Cook the livers until easily penetrated with a fork, then add onion vinegar and gravy.

  3. Season with salt, cayenne, sherry, and mushrooms if using; keep warm.

Cook and serve the omelette

  1. In a bowl, beat the eggs with milk just before cooking.

  2. Pour the egg mixture into a hot pan and cook until it sets.

  3. Add the prepared livers before folding the omelet and serve.

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 and rich when cooked through.
Eggs
Set into the structure of the omelette that holds the filling.
Dark rich gravy or sauce espagnole
Adds savoury depth and moisture to the livers.
Sherry
Adds a sweet, aromatic note that balances the richness of the livers.
Onion vinegar
Adds a sharp acidity that cuts through the richness of the livers.

The step that matters

Cook the livers until just penetrated, not overcooked. Livers turn grainy and dry when overcooked, while undercooked livers stay soft and unsafe. Checking with a fork shows when the proteins have set through the centre, so the timing is judged by texture rather than by the clock.

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.
