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 black pepper to keep flies away.
Wipe the mutton dry if washed.
Flour the mutton before roasting.
Roast and serve
Roast the mutton at a distance from the fire for 4 hours.
Move the mutton closer to the fire for the last 20-30 minutes to brown.
Baste the mutton regularly with its own fat to keep it moist.
Sprinkle lightly with coarse sea salt and ladle boiling water over it before serving.

What each ingredient does
- Mutton
- Forms the main body of the dish, and its own fat keeps the meat moist as it roasts.
- Flour
- Coats the surface so it can brown during roasting and helps form a crisp outer crust.
- Black pepper
- Adds sharp aroma and flavour to the outer surface of the meat.
The step that matters
Move the mutton closer to the fire for the last 20-30 minutes. Browning relies on high surface heat, so moving the joint nearer the fire only at the end gives colour without drying out the interior, which cooked slowly at a distance.
