Why it works: Beef and pepper are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 18,971 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Beef Kidney
Ingredients
Directions
Prepare
Cut the kidney into neat slices, about the size of a small veal cutlet.
Soak the slices in warm water for two hours, changing the water two or three times.
Remove the kidney from the water and place it on a clean cloth to dry.
Cook and serve
Heat clarified butter in a frying pan.
Fry the kidney slices until they are nicely browned.
Season with pepper and coarse sea salt before serving.

What each ingredient does
- Beef kidney
- Forms the main body of the dish, with a mild, tender texture once cooked through.
- Clarified butter
- Conducts heat for frying and encourages browning on the kidney slices.
The step that matters
Fry the kidney slices until nicely browned. Frying over sufficient heat drives the Maillard reaction, which browns the surface and builds savoury flavour. Crowding the pan or using too little heat makes the slices steam and turn grey instead of browning.
