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 ↓
Superior Receipt, for Roast 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 the oven to 350°F (175°C).
Rub the leg of mutton with coarse sea salt and black pepper.
Place the mutton in a roasting pan and dot with butter.
Add a little water to the pan to keep it moist.
Roast and rest
Roast in the oven for about 1.5 to 2 hours, basting occasionally.
Check for doneness and let rest before carving.

What each ingredient does
- Mutton
- Provides the main meat, which turns tender and juicy during slow roasting.
- Butter
- Adds fat that carries flavour and helps the surface brown and stay moist.
The step that matters
Check for doneness and let rest before carving. Meat cooked to the right internal temperature stays safe and tender, and resting lets juices redistribute so slices stay moist rather than running out on the board.
