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 salt, 1 teaspoon of pepper, 4 onions, 4 leeks, 2 carrots, 2 turnips, 3 cloves, and 1 burnt onion or 3 tablespoons of coloring.
Bring to a boil, skim off any scum, and then reduce heat to simmer.
Add a little cold water occasionally to keep the broth clear.
Simmer 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.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Breaks down during long simmering, releasing flavour and gelatin into the broth while the meat becomes tender.
- Onions
- Add savoury sweetness and aroma to the broth as they cook down.
- Leeks
- Contribute mild onion-like aroma and sweetness to the broth.
- Carrots
- Add natural sweetness and body to the broth.
- Turnips
- Add mild sweetness and earthy flavour to the broth.
The step that matters
Skimming the scum after the boil. Scum is coagulated protein and impurities that rise when the broth first boils. Skimming it keeps the broth clear and clean-tasting. Keeping the liquid at a gentle simmer, not a rolling boil, prevents fat and particles from being emulsified back into the broth.
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.
