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

What each ingredient does

Mutton kidneys
Provide the main meaty base that gives the gravy its body and savory flavor.
Butter
Adds fat for richness and a smooth, rounded mouthfeel.
Onion
Contributes aromatic sweetness and depth as it cooks into the liquid.

The step that matters

Remove the fat after straining. Fat from the simmered kidneys and butter floats on the surface and sets as a greasy layer when cooled. Skimming it off after straining leaves a clearer, smoother gravy with a cleaner flavor.

Swap the shallot

The recipe marks shallot as optional. How well each one fits the dish's main ingredients (mutton, butter, onion, pepper, meat):

  1. Potatofits better
  2. Leekfits about as well
  3. Capsicumfits about as well
  4. Shallotthe original

Fit is the average pairing score against mutton, butter, onion, pepper, meat. Candidates are from the same food group and used in at least 100 recipes.
