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 ↓
Roast 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 meat
Wipe the meat with a cloth dampened with cold water.
Dredge the meat with coarse sea salt, black pepper, and flour.
Place the meat on a rack in a baking pan or steamer.
Cover the bottom of the pan with flour.
Roast
Place the pan in a 400°F (200°C) oven.
Wait until the flour in the pan turns brown.
Pour enough hot water into the pan to cover the bottom.
Baste the meat often.
Cook the meat for 1 hour and 45 minutes.
Make the gravy and serve
When done, pour off the fat from the gravy.
Add 1 cup of boiling water to the remaining liquid in the pan.
Thicken the gravy with a paste made from 1 tablespoon of flour and a little cold water. Stir the gravy well.
Boil the gravy for 2-3 minutes.
Season the gravy with salt and pepper.
Strain the gravy.
Serve the roast leg of mutton with the gravy.

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 meat, cooked whole so the outside browns while the inside stays juicy.
- Flour
- Browns in the pan to flavour the drippings and later thickens the gravy.
- Coarse sea salt
- Seasons the meat surface and helps form a flavourful crust.
- Black pepper
- Adds a sharp, aromatic seasoning to the crust of the meat.
The step that matters
Wait until the flour in the pan turns brown. Flour that is pale stays raw-tasting, while flour browned past a rich colour turns bitter. Browning it fully before adding liquid builds the roasted flavour the gravy depends on.
