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

What each ingredient does

Pork kidneys
Provide the main meat and body of the dish.
Flour
Thickens the sauce as it cooks, giving it body.
White wine
Adds acidity and aroma, lifting the rich kidney flavour.
Butter
Adds richness and fat, carrying flavour and smoothing the sauce.
Shallots
Add sweet, savoury aromatic depth to the sauce.

The step that matters

Warm the wine without boiling. Boiling after the wine is added can make the sauce taste harsh and can cause the thickened sauce to break or turn grainy. Gentle warming keeps the wine's aroma and keeps the sauce smooth.

Swap the onion

How well each one fits the dish's main ingredients (pork, butter, pepper, parsley, shallot, flour, white wine):
