Oxford Receipt for Mutton Kidneys
Ingredients
Directions
Prepare
Trim the crusts off the bread and cut into uniform slices, about ½ inch thick and 2.5 to 4 inches long.
Fry the croutons in butter until golden, then remove and keep warm.
Split the kidneys in half, removing the skin and fat.
Season the kidneys with coarse sea salt and cayenne pepper.
Cook and serve
Arrange the kidneys in a clean frying pan and cook over medium heat for about 8 to 10 minutes, turning halfway through.
Serve the kidneys on the croutons immediately.

What each ingredient does
- Mutton kidneys
- Provide the tender, rich meat that forms the main body of the dish.
- Butter
- Fat that browns the bread croutons and adds richness and aroma.
- Bread
- Crisp, buttery base that holds the kidneys and absorbs their juices.
The step that matters
Cooking the kidneys in the pan. Kidneys become tough and rubbery if overcooked, so they should be turned once and served as soon as they are done while still tender and juicy.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
