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 ↓
Pot-au-feu
Ingredients
Directions
Prepare the meat
Roll the beef and mutton and tie them with string.
Put the meat in a large saucepan and pour the water over it.
Add the coarse sea salt.
Place the saucepan on a slow fire and remove the scum as it rises.
Tie the onion, mace, leek, celery, and chervil together in a bunch and add it to the saucepan.
Add pepper to taste, then the carrots and the turnips.
Cook the broth
Boil gently for 4 to 5 hours.
Remove the meat, the bunch of herbs, and the string from the meat.
Skim the broth.
Bread and serve
Cut bread into thin slices and place the sliced bread in a tureen.
Pour a portion of the broth gently through a sieve onto the bread.
Once the bread swells, pour in the remaining broth.
Chop the chervil finely and add it if desired.
Serve the vegetables and meat separately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Gives rich meaty flavor and body to the broth as it simmers slowly.
- Mutton
- Adds deeper savory flavor and richness to the broth during long simmering.
- Carrots
- Contribute sweetness and aroma to the broth as they cook.
- Turnips
- Add mild sweetness and soften during the long simmer, flavoring the broth.
- Leek
- Adds gentle onion-like aroma to the broth during simmering.
- Celery
- Adds savory aroma and background flavor to the broth.
The step that matters
Removing the scum as it rises. Skimming foam from the surface while the pot heats keeps the broth clear and free of impurities that would cloud it and taste bitter.
