Why it works: Leek and turnip match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,046 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Pot-au-feu
Ingredients
Directions
Make the broth
Combine the beef bone, lean beef, parsley, celery, leek, and cold water in a large pot.
Bring the mixture to a slow boil, adding salt and pepper.
Skim the surface thoroughly.
Simmer gently for 2 hours.
Add the carrot, onion, turnip, and tomatoes.
Cook for an additional 5 hours.
Do not stop boiling or add water during cooking.
Clarify and rest
Strain the soup through a fine sieve.
Let the strained soup stand overnight.
In the morning, remove the fat.
Carefully pour off the top from the sediment.
Serve
Serve the vegetables in a separate dish.
Pour the hot soup over diced or squared browned bread in the tureen.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean beef
- Releases meaty flavour into the broth during long, slow cooking.
- Beef bone
- Releases gelatin and savoury depth into the broth as it simmers.
- Onion
- Adds sweetness and aroma as it softens in the broth.
- Leek
- Adds a mild, onion-like aroma to the broth.
- Carrot
- Adds gentle sweetness to the broth.
- Tomatoes
- Add acidity and savoury depth to the broth.
The step that matters
Skim the surface thoroughly. Foam and impurities rise to the surface as the broth first heats. Removing them keeps the broth clear and clean-tasting, and the simmer should stay gentle so fat and particles do not get mixed back in.
Swap the tomato
How well each one fits the dish's main ingredients (beef, parsley, celery, leek, carrot, onion, turnip):
- Parsnipfits better
- Chivefits better
- Lettucefits better
- Tomatothe original
Fit is the average pairing score against beef, parsley, celery, leek, carrot, onion, turnip. Candidates are from the same food group and used in at least 100 recipes.
