Why it works: Carrot and turnip 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 ↓
Haricot of Mutton or Lamb
Ingredients
Directions
Prepare the meat
Trim the fat from the leg of lamb or mutton and place it in a kettle.
Cover the meat with water and skim off any foam as it boils.
Simmer
Cover and simmer for 4 hours, salting it halfway through.
Add the chopped onion, carrot, and turnip to the kettle.
Allow the water to reduce until only enough remains for gravy.
Make the gravy and serve
Thicken the remaining liquid with browned flour.
Stir in the tomato ketchup and bring to a boil.
Serve the meat on a hot platter and pour the gravy over it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leg of lamb or mutton
- Provides the main meat, which becomes tender through long, slow simmering.
- Browned flour
- Thickens the reduced cooking liquid into a gravy.
- Tomato ketchup
- Adds sweetness and acidity to the gravy.
- Onion
- Adds savoury depth and aroma to the cooking liquid.
The step that matters
Skimming the foam as the water boils. Foam carries impurities and scum from the meat into the liquid. Removing it early keeps the broth clear and the gravy clean-tasting.
Swap the tomato
How well each one fits the dish's main ingredients (lamb, meat, onion, carrot, turnip, flour, ketchup):
- Leekfits better
- Okrafits better
- Shallotfits better
- Tomatothe original
Fit is the average pairing score against lamb, meat, onion, carrot, turnip, flour, ketchup. Candidates are from the same food group and used in at least 100 recipes.
