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 meat and tie it with string.
Place the meat in a large saucepan and pour water over it.
Add salt, onion, mace, leek, celery, chervil, herbs, and pepper.
Put the saucepan on a slow fire and skim off any scum that rises.
Cook and simmer
Boil gently for 4 to 5 hours.
Finish and serve
Remove the meat and the bunch of herbs, then take off the string from the meat.
Skim the broth and slice the meat thinly into a tureen.
Pour a portion of the broth gently through a sieve over the bread until it swells, then add the remaining broth.
Chop the vegetables finely and add them 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
- Long gentle simmering turns the tough cuts tender and flavours the broth.
- Mutton
- Slow cooking softens the meat and adds rich, savoury depth to the broth.
- Bread
- Soaking in hot broth lets it swell and soften, absorbing liquid for a tender texture.
The step that matters
Boil gently for 4 to 5 hours. A rolling boil toughens meat proteins and clouds the broth. Keeping the liquid at a gentle simmer lets collagen break down slowly and keeps the broth clear.
Swap the mace
How well each one fits the dish's main ingredients (beef, mutton, onion, leek, celery, chervil, pepper):
- Tarragonfits better
