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 ↓
French Pot Au Feu
Ingredients
Directions
Make the broth
In a large pot, combine 1 gallon of water and 4 pounds of beef.
Add 3 teaspoons of coarse sea salt, 1 teaspoon of black pepper, 4 chopped onions, 4 chopped leeks, 2 chopped carrots, 2 chopped turnips, and 3 cloves.
If using, add 1 burnt onion or 3 tablespoons of coloring.
Bring to a boil, skim off any scum, and reduce heat to simmer.
Add a little cold water occasionally to keep the broth clear.
Simmer for 4 hours.
Serve
Place sliced bread in a tureen.
Pour the broth and some vegetables over the bread.
Serve the meat separately with remaining vegetables.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Slow simmering breaks down connective tissue, making the meat tender and flavouring the broth.
- Onions
- Release sweetness and savoury depth into the broth as they cook.
- Leeks
- Add a mild, sweet onion-like flavour to the broth.
- Carrots
- Add sweetness and body to the broth as they soften.
- Turnips
- Add a mild sweetness and earthy flavour to the broth.
- Bread
- Soaks up the broth, becoming soft and flavourful when served in it.
The step that matters
Keep the simmer gentle and skim the scum. A rolling boil makes the broth cloudy and can toughen the meat. Skimming removes impurities that would otherwise cloud and taint the broth, and occasional cold water helps proteins clump and settle.
Swap the clove
How well each one fits the dish's main ingredients (beef, pepper, onion, leek, carrot, turnip, bread):
- Celeryfits better
- Parsleyfits better
- Thymefits better
- Clovethe original
Fit is the average pairing score against beef, pepper, onion, leek, carrot, turnip, bread. Candidates are from the same food group and used in at least 100 recipes.
