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

What each ingredient does

Veal kidneys
Form the main body of the dish, cooked tender in thin slices.
Flour
Coats the slices so they brown and form a light crust while frying.
Butter
Fat for frying that carries heat and adds richness and browning.
Champagne or white wine
Adds acidity and aroma, lifting the flavour of the frying pan.

The step that matters

Fry the slices in butter over medium heat. Kidney is delicate and overcooks quickly, turning firm and rubbery. Medium heat lets the butter brown the flour coating without burning, and the slices cook through gently.

Swap the onion

How well each one fits the dish's main ingredients (veal, pepper, flour, parsley, butter, champagne):

  1. Shallotfits better
  2. Carrotfits better
  3. Chivefits better
  4. Onionthe original

Fit is the average pairing score against veal, pepper, flour, parsley, butter, champagne. Candidates are from the same food group and used in at least 100 recipes.
