Why it works: Lemon and pepper 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 ↓
Roast Shoulder 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 shoulder of lamb in a roasting pan with more water than usual.
Roast and finish
Roast slowly until nearly done, basting frequently with gravy.
Five minutes before finishing, baste with melted butter mixed with lemon juice.
Dredge the lamb with salt, pepper, and flour, then brown lightly.
For variation, remove the bone and fill the cavity with a mixture of bread crumbs, butter, salt, and pepper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shoulder of lamb
- Forms the main meat that cooks slowly and becomes tender with long, gentle roasting.
- Butter
- Adds richness and helps the surface brown and taste rounded when basted.
- Lemon juice
- Adds acidity that brightens the rich flavor of the lamb and butter.
- Flour
- Dries the meat surface so it browns lightly and forms a more even crust.
- Bread crumbs
- Absorbs butter and juices in the cavity, adding body and a soft stuffing texture.
The step that matters
Dredging and browning the lamb. Flour coating must be dry and even before browning, or it can clump or scorch instead of forming a light, golden crust.

Fit is the average pairing score against lamb, butter, pepper, flour, bread. Candidates are from the same food group and used in at least 100 recipes.
