Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Kidneys
- Provide the main meat, which becomes tender during gentle simmering in the gravy.
- Browned flour
- Thickens the gravy so it clings to the kidneys and toast.
- Butter
- Adds fat and richness to the pan for cooking the kidneys and onion.
- Gravy
- Supplies the savory liquid base that the kidneys simmer in.
- Lemon juice
- Adds acidity that brightens the rich, savory gravy.
The step that matters
Simmer gently with the lid on. Gentle, covered simmering keeps the kidneys tender and prevents toughening, since rapid boiling makes the meat firm and rubbery.
Swap the onion
How well each one fits the dish's main ingredients (butter, mace, nutmeg, lemon, flour):
- Arrowrootfits better
- Shallotfits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against butter, mace, nutmeg, lemon, flour. Candidates are from the same food group and used in at least 100 recipes.
