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 ↓
Breast of Lamb, with Peas
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 oven to 350°F (175°C).
Season the lamb breast with salt and pepper.
Place the lamb in a roasting pan and add butter on top.
Roast and serve
Roast in the oven for about 1 hour, basting occasionally.
In the last 15 minutes, add the fresh peas to the pan.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb breast
- Provides the main protein, which becomes tender and juicy during slow roasting.
- Fresh peas
- Add sweetness and a fresh, green flavour, and cook quickly in the pan juices.
- Butter
- Adds fat and richness, helping the meat brown and stay moist while it roasts.
The step that matters
Adding the fresh peas in the last 15 minutes. Fresh peas cook quickly and turn dull and mushy if left in the oven too long. Adding them late keeps them bright green and tender-crisp while they absorb the pan juices.
Swap the peas
How well each one fits the dish's main ingredients (lamb, pepper, butter):
- Almondfits better
- Beansfits better
- Sesamefits about as well
- Peasthe original
Fit is the average pairing score against lamb, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
