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
Combine 1 gallon of water and 4 pounds of beef in a large pot.
Add 3 teaspoons coarse sea salt, 1 teaspoon black pepper, 4 onions, 4 leeks (cut into pieces), 2 carrots, 2 turnips, and 3 cloves.
If using, add 1 burnt onion or 3 tablespoons coloring.
Bring to a boil, skim off any scum, and reduce heat to simmer.
Cook for 4 hours, adding a little cold water occasionally to keep the broth clear.
Serve
Serve the broth with sliced bread and the vegetables, keeping the meat separate.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Gives the broth its rich, savory flavor as it simmers.
- Onions
- Add sweetness and aromatic depth to the broth as they cook down.
- Leeks
- Contribute a mild, sweet onion flavor to the broth.
- Carrots
- Add natural sweetness and body to the broth.
- Turnips
- Add mild sweetness and earthy flavor to the broth.
The step that matters
Skimming the scum after the boil. Scum rising from the meat contains coagulated proteins and impurities. Skimming it off keeps the broth clear and clean-tasting, and the gentle simmer prevents it from clouding again.
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.
