Why it works: Lamb and chicken match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 626 recipes. Both carry 2,4-nonadienal, 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 the oven to 350°F (175°C).
Season the breast of lamb with salt and pepper.
In a skillet, melt the butter and sauté the chopped onion until translucent.
Roast
Place the lamb in a roasting pan and add the sautéed onion and chicken broth.
Cover and roast for 1 hour, basting occasionally.
Add the peas during the last 15 minutes of cooking.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb breast
- Is the main cut, becoming tender and juicy during slow covered roasting.
- Peas
- Add sweetness and a fresh, green flavor, cooked briefly at the end.
- Butter
- Adds richness and helps the onion soften and turn translucent in the skillet.
- Onion
- Adds savory sweetness and aroma as it softens in butter.
- Chicken broth
- Provides moisture in the roasting pan, keeping the lamb from drying out.
The step that matters
Covered roasting with basting. Covering the lamb traps moisture so the slow roast stays tender, while basting returns juices to the surface. Adding peas only in the last 15 minutes keeps them bright green and tender rather than overcooked.

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