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 Roast a Leg of Mutton
Ingredients
Directions
Prepare
Hang the leg of mutton in a cool, airy place for several days.
Remove the kernel and dry the flap.
Dredge the mutton with pepper to protect it from flies.
If washed, dry it thoroughly.
Flour it before roasting.
Roast and serve
Roast the mutton at a distance from the fire for four hours.
Move it closer for the last 20-30 minutes to brown.
Baste the mutton with its own fat throughout the cooking process.
Once done, sprinkle lightly with salt.
Ladle a spoonful or two of boiling water over it before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leg of mutton
- Forms the main meat and carries the flavour and juiciness of the roast.
- Flour
- Coats the surface so it can brown during roasting.
- Pepper
- Dredged over the meat as a protective coating against flies.
- Coarse sea salt
- Seasons the cooked surface after roasting.
The step that matters
Move it closer for the last 20-30 minutes to brown. Browning relies on high surface heat, which is only reached near the end. Moving the meat too early or too late can leave it pale or overcooked on the outside.
