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

What each ingredient does

Liver
Forms the main body of the dish, giving it its rich, meaty flavour.
Browned flour
Thickens the cooking liquid into a gravy as it heats.
Hard-boiled eggs
Add soft, finely cut texture that blends into the gravy.
Butter
Adds fat and richness to the gravy and carries flavour.

The step that matters

Adding the browned flour and dry mustard. Flour must be fully dispersed in the hot liquid and stirred well, or it will clump and leave floury lumps instead of a smooth, evenly thickened gravy.

Swap the mustard

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

  1. Shallotfits better
  2. Capsicumfits better
  3. Chivefits better
  4. Mustardthe original

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