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 and Loin of Lamb
Ingredients
Directions
The book says “a hot oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.
Prepare
Wipe the leg of lamb with a damp cloth.
Place the lamb on a meat rack and season with salt and pepper.
Set the lamb in a dripping pan.
Roast
Roast the lamb in a hot oven (400°F / 200°C) for 1.5 hours, basting every 15 minutes.
Remove the lamb from the pan when done.
Make the gravy and serve
Add flour and hot water to the pan.
Let the mixture boil for about 3 minutes.
Serve the lamb in a gravy bowl.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb leg
- Forms the main body of the dish and provides the meat that is roasted and served.
- Flour
- Thickens the pan juices into a gravy as it boils with the liquid.
- Hot water
- Mixes with the pan drippings and flour to form a thinner gravy.
The step that matters
Basting the lamb every 15 minutes. Regular basting spoons drippings over the surface, keeping the meat moist and helping the outside brown during the long roast.
