Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Mutton Kidneys Broiled
Ingredients
Directions
Prepare
Skin and split the mutton kidneys without separating them completely.
Skewer them through the outer edge to keep them flat.
Broil
Place the opened sides facing the fire, which should be clear and brisk.
After four minutes, turn them over and sprinkle with coarse sea salt and cayenne pepper.
Cook for an additional three minutes, then remove from the fire.
Finish and serve
Add a piece of butter inside each kidney and squeeze lemon juice over them.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton kidneys
- Form the main body of the dish, cooking to a tender, meaty texture over direct heat.
- Butter
- Adds richness and moisture inside the kidneys as they cook and melt.
- Lemon juice
- Adds acidity that brightens the rich, fatty flavour of the kidneys.
The step that matters
Turning and timing on the fire. Kidneys overcook quickly and turn tough and rubbery. Cooking the cut sides first over a clear, brisk fire sears them, and the timed turn cooks them through while keeping them tender.
“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.
