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 drying the flap.
Dredge the mutton with pepper to keep flies away if it's warm.
Wipe the mutton dry if washed, then flour it before roasting.
Roast and serve
Roast the mutton at least 1 foot from the fire for 4 hours, moving it closer for the last 20-30 minutes for color.
Baste constantly with its own fat to ensure a good roast.
Sprinkle lightly with coarse sea salt and ladle a spoonful or two of boiling water over it before serving.

What each ingredient does
- Mutton
- Forms the main body of the roast, with its own fat keeping the meat moist as it cooks.
- Flour
- Coats the surface so it browns and forms a crisp, colored crust during roasting.
- Pepper
- Dredged onto the meat to add flavor and help keep flies away while it hangs.
The step that matters
Basting constantly with its own fat. Basting spreads melted fat over the surface, keeping the meat moist and helping the crust brown evenly over a long roast.
