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
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat your oven to 350°F (175°C).
Season the leg of mutton with coarse sea salt and black pepper.
Rub the meat with butter or oil for a nice crust.
Roast and rest
Place the leg in a roasting pan and roast for about 1.5 to 2 hours, depending on the size.
Let it rest for 15 minutes before carving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leg of mutton
- Is the main cut of meat that is roasted and carved into servings.
- Butter or oil
- Carries heat to the surface and helps the outside brown into a crust.
The step that matters
Letting the leg rest before carving. Heat pushes juices toward the center during roasting. Resting lets the muscle fibers relax so juices settle back through the meat instead of running out when cut.
