Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Beoiled Mutton Kidneys
Ingredients
Directions
Prepare the kidneys
Split the kidneys open lengthwise without dividing them; remove the skin and fat.
Run a fine skewer through the points and across the back of the kidneys to keep them flat while broiling.
Season the kidneys with coarse sea salt and cayenne pepper.
Broil and fry
Broil the kidneys over a clear brisk fire with the cut sides facing the heat for 4-5 minutes.
Turn the kidneys and cook for an additional 4-5 minutes.
Meanwhile, fry the croutons in a little clarified butter until golden and keep them hot.
Arrange the split kidneys in a clean frying pan and pour clarified butter over them.
Fry the kidneys over a brisk fire until cooked through.
Serve
Place each half of the kidney on a crouton.
Make a sauce in the pan using gravy instead of water, adding a little wine or ketchup if available.
Pour the sauce around the croutons and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton kidneys
- Main protein; they cook quickly and turn tender when broiled or fried briefly.
- Clarified butter
- Fat that fries the kidneys and croutons evenly and adds richness and browning.
- Bread croutons
- Absorbent base that holds the kidneys and soaks up the pan sauce.
- Gravy
- Liquid base for the sauce, adding savoury depth and body.
The step that matters
Cooking the kidneys through without overcooking. Kidneys become tough and rubbery when overcooked, so the cook must watch the brisk heat closely and stop once they are just cooked through.
