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, removing the kernel and wiping the flap dry.
Dredge the mutton with black pepper, especially in warm weather.
Flour the mutton after washing it before placing it on the spit.
Roast
Roast the mutton slowly, keeping it about 2 feet from the fire for 4 hours.
Baste the mutton constantly with its own fat to ensure a good roast.
Move the mutton closer to the fire for the last 20-30 minutes to brown it.

What each ingredient does
- Mutton leg
- Provides the main meat, which becomes tender and juicy with slow roasting.
- Flour
- Coats the surface so it can take on a crisp, browned crust in the fire.
- Black pepper
- Adds a sharp, aromatic seasoning to the outer surface of the meat.
- Fat from the mutton
- Basting with its own fat moistens the surface and helps it roast evenly.
The step that matters
Keeping the mutton far from the fire during slow roasting. Cooking slowly at a distance heats the meat through gently and avoids a burnt outside before the centre is done. The closer browning is saved for the end, when the surface can crisp without overcooking the interior.
