What each ingredient does
- Sheep's kidneys
- Form the main body of the dish, becoming tender when simmered gently.
- Flour
- Coats the kidneys for browning and later thickens the cooking liquid.
- Dripping
- Fat for frying the floured kidneys, adding richness and browning them.
- Stock or water
- Forms the liquid that simmers with the kidneys to make a sauce.
The step that matters
Frying the floured kidneys until golden brown. Flour and fat brown through the Maillard reaction and build flavour. Frying too gently or overcrowding the pan steams the kidneys, leaving them pale and bland before the liquid is added.
