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

What each ingredient does

Calf's liver
Forms the main body of the dish, and browning it adds savoury flavour.
Flour
Coats the liver so it browns, and helps thicken the sauce.
Hard-boiled eggs
Chopped eggs add richness and body to the mixture.
Mustard
Adds sharpness that balances the richness of the liver and cream.
Cream or milk
Adds moisture and creaminess, giving a smooth, rich mixture.

The step that matters

Letting the mixture boil once. Cream and milk can curdle, scorch, or turn grainy if they boil hard or for too long. A single brief boil keeps the mixture smooth and thickened.

Swap the mustard

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

  1. Spinachfits better
  2. Chivefits about as well
  3. Asparagusfits about as well
  4. Mustardthe original

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