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

What each ingredient does

Kidneys
The main protein; cooking sears the outside and sets the texture as it firms.
Butter
Conducts heat in the pan and adds richness and browning to the kidneys.
Sauce
Adds savoury, tangy flavour and helps form the gravy spooned over the kidneys.
Thin, dry toast
Provides a crisp base that holds the kidneys and soaks up the gravy.

The step that matters

Cook each side for an equal time. Kidneys turn tough and rubbery when overcooked, so turning them once and timing both sides equally helps them cook evenly and stay tender.
