What each ingredient does
- Beef kidneys
- Form the main body of the dish, cooking to a tender, browned slice.
- Clarified butter
- Conducts heat for even browning and adds a rich, nutty fat flavour.
The step that matters
Cook the kidneys until browned on each side. Dry slices brown rather than steam. Patting them dry before cooking lets the butter sear the surface, while overcooking toughens the meat.
