Why it works: Mutton and pepper are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 5,442 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
To Boast a Leg of Mutton
Ingredients
Directions
Prepare
Hang the leg of mutton in a cool, airy place for several days, removing the kernel and drying the flap.
Dredge the mutton with pepper to keep flies away.
If washed, dry it thoroughly and flour it before roasting.
Roast and serve
Roast the mutton at a distance from the fire for four hours, moving it closer for the last 20-30 minutes to brown.
Baste constantly with its own fat to ensure a good roast.
Sprinkle lightly with salt and ladle boiling water over it before serving.

What each ingredient does
- Leg of mutton
- Is the main cut of meat, whose fat and lean muscle define the dish's flavour and texture.
- Flour
- Coats the surface so it browns and crisps during roasting.
- Coarse sea salt
- Seasons the meat and adds a savoury finish at the end.
The step that matters
Moving the mutton closer to the fire for the last 20-30 minutes. Heat close to the fire drives browning on the surface through the Maillard reaction, but too early or too long can scorch the exterior before the interior is cooked. Timing the move at the end gives colour without burning.
