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 onions, 4 leeks, 2 carrots, 2 turnips, 3 cloves, and 1 burnt onion or 3 tablespoons of coloring.
Set the pot on the fire and skim off any scum that forms.
Place the pot to the side of the fire and occasionally add a drop of cold water to keep the broth clear.
Boil for 4 hours.
Serve
Slice bread and place it in a tureen, then pour the broth and some vegetables over it.
Serve the meat separately with the remaining vegetables on the side.

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, so the meat becomes tender and flavours the broth.
- Onions
- Burnt onion or coloring gives the broth its deep amber color and a toasty aroma.
- Leeks
- Add sweet, mild aromatic flavour to the broth as they simmer.
- Bread
- Soaks up the hot broth, becoming soft and absorbent in the tureen.
The step that matters
Skimming and keeping the broth off a hard boil. Scum is coagulated protein and impurities that cloud the broth and taste bitter if left in. Keeping the pot at a gentle simmer, with occasional cold water, lets fat and particles settle so the broth stays clear.
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.
