Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef kidneys
- Form the main body of the dish, becoming tender when cooked gently and briefly.
- White wine
- Adds acidity and aroma, and helps loosen the cooking juices into a sauce.
- Butter
- Adds richness and fat, carrying flavour and giving the sauce a smooth finish.
- Flour
- Thickens the cooking liquid into a light sauce that coats the kidneys.
The step that matters
Cooking the kidneys over moderate heat. Kidney turns firm and rubbery if overcooked. Moderate heat, with constant stirring, cooks the meat evenly so it stays tender while the sauce thickens.
Swap the nutmeg
How well each one fits the dish's main ingredients (beef, white wine, butter, flour, pepper, parsley):
- Thymefits better
- Tarragonfits better
- Marjoramfits better
- Nutmegthe original
Fit is the average pairing score against beef, white wine, butter, flour, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
