Why it works: Turnip and carrot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,002 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Roast Lamb
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.
Roast the lamb
Preheat the oven to 400°F (200°C).
Roast the lamb for 2 hours.
Once cooked, separate the shoulder from the ribs using a sharp knife.
Add butter, salt, and lemon juice over the meat.
Restore the shoulder to its place.
If desired, place slices of turnip and carrot over the lamb under the paper.
Serve
Serve with stewed green peas, salad, and mint sauce.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb shoulder
- Provides the main meat, which becomes tender and juicy through slow roasting.
- Butter
- Adds fat and moisture over the meat, helping it brown and taste rich.
- Lemon juice
- Adds acidity that brightens the rich flavour of the lamb.
- Turnip and carrot
- Optional slices that add sweetness and flavour as they cook beneath the lamb.
The step that matters
Separating the shoulder from the ribs. Cutting once the lamb is cooked, with a sharp knife, keeps the meat intact and clean; a dull knife tears the tender fibres and crushes juices out.
Swap the lemon
How well each one fits the dish's main ingredients (lamb, butter, turnip, carrot, peas, mint, sauce):
- Limefits about as well
- Lemonthe original
- Pumpkinfits less well
- Cherryfits less well
Fit is the average pairing score against lamb, butter, turnip, carrot, peas, mint, sauce. Candidates are from the same food group and used in at least 100 recipes.
