Why it works: Leek and chervil match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 148 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Cooking-stock
Ingredients
Directions
Prepare the meats
Cut the beef and veal into pieces.
Place the meats in a large stockpot.
Add the hens and giblets, then cover with water or second broth.
Make the broth
Heat the stockpot on the fire and skim the liquid carefully.
Once it bubbles, remove it from the heat.
After one hour, add carrots, leeks, chervil, parsley, cloves, and peppercorns.
Continue to simmer gently.
Once the meats are cooked, remove them from the pot.
Strain the broth through a sieve and skim off the fat.
Let the broth settle, then decant it into two saucepans.
Reduce and store
Reduce the broth over high heat until slightly thickened.
Mix the two parts in a narrow stewpan and skim until it reaches a light sauce consistency.
Pour into vessels and store for later use.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leg of beef
- Provides the main meaty flavour and body to the stock as it simmers.
- Veal
- Adds gelatin-rich body and a delicate flavour to the finished stock.
- Hens
- Contribute savoury flavour and body to the broth during long simmering.
- Carrots
- Add gentle sweetness and aromatic depth to the stock.
- Leeks
- Add mild onion-like sweetness and aroma to the broth.
The step that matters
Skimming the liquid as it heats. Impurities and proteins rise to the surface as the liquid warms. Removing them early keeps the stock clear and prevents a cloudy, greasy result.
Swap the clove
How well each one fits the dish's main ingredients (beef, veal, liver, carrot, leek, chervil, parsley):
- Thymefits better
- Tarragonfits better
- Marjoramfits better
- Clovethe original
Fit is the average pairing score against beef, veal, liver, carrot, leek, chervil, parsley. Candidates are from the same food group and used in at least 100 recipes.
