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

What each ingredient does

Kidneys
Form the main protein that cooks to a tender, savoury centre.
Butter
Adds fat for frying, carrying flavour and helping the kidneys brown.
Harvey's sauce
Adds a sharp, savoury tang that seasons the finished kidneys.
Thin dry toast
Provides a crisp base that soaks up the pan gravy.

The step that matters

Cook the kidneys one side, then the other, for equal time. Kidneys overcook quickly and turn tough and rubbery. Cooking each side for the same time gives even doneness, and removing them promptly keeps them tender.
