Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sheep's kidneys
- Form the main body of the dish, cooked tender in a quick sauté.
- Bacon
- Adds savoury fat and flavour to the pan that the kidneys cook in.
- Butter
- Carries the fat for frying and adds richness to the sauce.
- Flour
- Thickens the pan juices into a sauce when heated with the liquid.
- White champagne
- Adds acidity and liquid, deglazing the pan and lightening the sauce.
- Lemon juice
- Adds acidity that brightens the sauce and balances the richness.
The step that matters
Boiling the sauce once to cook the flour. Flour must be heated long enough to cook out its raw taste and thicken the sauce. Boiling it briefly does this, but prolonged boiling can toughen the kidneys and make the sauce too thick.
