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 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Season the lamb with salt and pepper.
Place the lamb in a roasting pan and rub with butter.
Roast and serve
Roast in the oven for about 1.5 hours, or until the internal temperature reaches 145°F (63°C).
Let the lamb rest for 10 minutes before carving.

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, becoming tender and juicy as it cooks slowly.
- Butter
- Adds fat that carries flavour and helps the surface brown in the oven.
The step that matters
Let the lamb rest for 10 minutes before carving. Resting lets muscle fibres relax and redistribute juices, so the meat stays moister when sliced instead of losing liquid onto the board.
