Mutton Kidneys Deoiled
Ingredients
Directions
Prepare
Skin and split the mutton kidneys without separating them completely.
Skewer them through the outer edge to keep them flat.
Cook and serve
Place the opened sides first over a clear, brisk fire for 4 minutes.
Turn them over, sprinkle with coarse sea salt and cayenne pepper, and cook for an additional 3 minutes.
Remove from the fire, place a piece of butter inside each kidney, squeeze lemon juice over them, and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton kidneys
- Provide the main meat, which turns tender and juicy when cooked quickly over high heat.
- Butter
- Adds richness and moisture, melting into the kidney once it comes off the fire.
- Lemon juice
- Adds acidity that brightens the rich, savoury flavour of the kidney.
The step that matters
Turn them over, sprinkle with coarse sea salt and cayenne pepper, and cook for an additional 3 minutes.. Salt seasons the meat and draws moisture to the surface, where it helps form a browned crust. Overcooking past the set time dries the kidney and makes it tough.
