Why it works: Butter and pepper are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 85,593 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Kidneys, Sauted
Ingredients
Directions
Prepare
Split the kidneys lengthwise without detaching the halves.
Insert a skewer through the kidneys to keep them open.
Brush the kidneys with salad oil or oiled butter.
Season with coarse sea salt and black pepper.
Cook and serve
Grill the kidneys cut side down over a clear fire for 5 to 8 minutes, depending on size.
Place a kidney on each hot crouton and add a small pat of Maitre d'Hotel butter on top.
Serve immediately.

What each ingredient does
- Kidneys
- Form the main protein that is cooked over direct heat until browned and tender.
- Salad oil or oiled butter
- Coats the surface so the kidneys brown evenly and do not stick to the grill.
- Maitre d'hotel butter
- Melts over the hot kidney, adding richness and a savory, herbed flavor.
- Croutons
- Hold the kidneys up and soak up the melted butter and juices.
The step that matters
Grill cut side down over a clear fire. Direct, steady heat browns the cut surface quickly and sets it, while the interior cooks gently. A flare-up or uneven fire can scorch the outside before the centre is done, so keep the fire clear and check the time against the kidney's size.
