Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Fore-quarter of Lamb, Roasted
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the lamb
Remove the scrag from the shoulder, saw off the shank-bone and the chine bone along the fillet of the leg.
Partially saw the rib-bones and break the shoulder-bone, then twist it round and fasten it with a skewer from beneath the breast.
Twist paper around the shank-bone.
Roast
Cover the lamb with buttered paper.
Roast it in a 400°F (200°C) oven for about 2.5 hours.
Dredge flour over the lamb just before removing it from the oven.
Baste the joint with butter to make it froth up.
Season and serve
Sprinkle cayenne pepper between the shoulder and ribs.
Place the joint on a hot dish and pour a little gravy from the dripping pan over it.
Serve with mint sauce in a sauce boat and lemon on the side.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb
- Forms the main body of the dish, and its fat and connective tissue provide flavour and juiciness as it roasts.
- Butter
- Adds fat that promotes browning and a golden, frothy surface when basted over the joint.
- Flour
- Dredged over the surface near the end of roasting to help form a crisp, browned crust.
The step that matters
Dredging flour just before removing the lamb from the oven. Flour applied too early can scorch or burn before the roast finishes, while applied at the end it browns and crisps the surface quickly in the hot oven.
Swap the mint
How well each one fits the dish's main ingredients (lamb, butter, flour, pepper, sauce, lemon):
- Parsleyfits better
- Capersfits better
- Tarragonfits better
- Mintthe original
Fit is the average pairing score against lamb, butter, flour, pepper, sauce, lemon. Candidates are from the same food group and used in at least 100 recipes.
