Why it works: Parsley and carrot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Bouillon a LA Moderne
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the broth
Combine 4 liters of cold water and 2 kg of lean beef with bones in a pot, filling it three-quarters full.
Bring to a boil, skimming off any foam that forms.
Add ½ teaspoon coarse sea salt, 1 clove, 2 bay leaves, a few peppercorns, 1 celery stalk, 1 parsley root, 1 onion, 1 turnip, and 1 carrot.
Reduce heat and simmer for 3 to 4 hours until you have 3 liters of broth.
Finish
Strain the broth before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean beef with bones
- Releases collagen and gelatin into the water, giving the broth body and a rich mouthfeel.
- Onion
- Adds savory sweetness and aroma as its sugars brown slightly during simmering.
- Carrot
- Contributes subtle sweetness and aromatic depth to the simmered broth.
- Celery stalk
- Adds aromatic, vegetal flavor that rounds out the broth.
- Parsley root
- Adds earthy, herbal aroma to the broth.
The step that matters
Skimming the foam as it comes to a boil. Foam is made of coagulated proteins and impurities. Removing it early keeps the broth clear and prevents off-flavors from being reabsorbed as it simmers.
Swap the clove
How well each one fits the dish's main ingredients (beef, celery, parsley, onion, turnip, carrot):
- Thymefits better
- Marjoramfits better
- Tarragonfits better
- Clovethe original
Fit is the average pairing score against beef, celery, parsley, onion, turnip, carrot. Candidates are from the same food group and used in at least 100 recipes.
