Why it works: Lamb and pepper are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 3,165 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Roast Leg of Lamb
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.
Prepare
Preheat your oven to 350°F (175°C).
Place the leg of lamb in a covered roaster.
Pour 1 cup of boiling water over the lamb and cover it.
Roast
Cook for about 15 minutes per pound.
Twenty minutes before it is done, remove the cover.
Rub the lamb all over with butter, then dredge with pepper, coarse sea salt, and flour.
Brown the lamb in the oven until golden.
Serve
Serve with mint sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leg of lamb
- Is the main meat, cooked slowly in steam and then browned for a golden surface.
- Butter
- Adds fat and helps the flour and seasonings stick and brown in the oven.
- Flour
- Dries the surface of the meat and helps form a browned crust.
The step that matters
Remove the cover 20 minutes before done. Uncovering lets moisture escape and the surface dry out, so the lamb can brown. Leaving the cover on until the end would leave the crust pale and soft.
