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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Browned with butter, it forms a roux that thickens the soup.
- Butter
- Melted and browned with flour to start the roux, adding nutty flavour.
- Leg of beef
- Long simmering breaks down its connective tissue, enriching the broth with body.
- Onions
- Softened during long simmering, they add sweetness and savoury depth to the broth.
- Sherry
- Added at the end, it contributes acidity and aroma to the finished soup.
The step that matters
Browning the flour while stirring constantly. Flour browns unevenly and can scorch quickly over direct heat. Constant stirring keeps it cooking evenly, so the roux thickens well and tastes nutty rather than bitter.
Swap the onion
How well each one fits the dish's main ingredients (beef, veal, carrot, turnip, pepper, butter, flour):
- Leekfits better
- Parsnipfits better
- Shallotfits about as well
- Onionthe original
Fit is the average pairing score against beef, veal, carrot, turnip, pepper, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
