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

What each ingredient does

Beef kidneys
Provide the main meat, which becomes tender and firm when fried through.
All-purpose flour
Coats the slices so they brown and form a crisp outer layer when fried.
Lard
Conducts heat for frying and adds richness and browning to the surface.
Wine
Deglazes the pan, lifting browned bits into the liquid to build the gravy's flavour.
Lemon juice
Adds acidity that brightens the gravy and balances the richness of the fat.
Butter
Adds fat and a smooth body to the gravy as it finishes in the pan.

The step that matters

Frying the kidneys until cooked through. Kidneys turn tough and rubbery if overcooked, and undercooked meat is unsafe. Frying over steady heat and checking for doneness keeps the slices tender while ensuring they are fully cooked.

Swap the onion
