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 ↓
Boned Leg of Mutton
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the leg
Remove the bone from the leg of mutton and wipe the meat inside and out with a wet cloth.
Sprinkle the inside with coarse sea salt.
Stuff and sew the leg.
Roast
Place the leg on a rack in a dripping pan.
Add some kidney suet on the meat and in the pan.
Dredge the meat with salt, pepper, and flour.
Bake in a hot oven at 400°F (200°C).
Baste as soon as the flour is browned, then repeat basting often.
Bake for one hour for rare or one hour and a quarter for well done.

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 body of the roast, and its lean meat cooks to tenderness and juiciness.
- Kidney suet
- Adds fat that bastes the meat as it melts, keeping it moist and adding richness.
- Flour
- Dredged over the meat, it browns in the oven to form a crisp, golden crust.
The step that matters
Basting once the flour is browned. Basting too early can wash off the flour coating before it sets, while waiting until it browns builds a crust. Repeated basting then keeps the surface moist and the browning even.
