Why it works: Chervil and chard share more aroma than cooks usually use. They rank in the top 3% of all ingredient pairs, and 7 recipes mention both. Both carry coumarin, which smells sweet, hay. The science ↓

Ingredients
Directions
Prepare the broth
Remove the gills and blood parts from the chicken and place it in a small pot.
Add 8 cups of cold water, then add the chopped carrot, turnip, and salt.
Bring to a gentle boil and simmer for 2 hours.
Add the greens and serve
Add the cleaned lettuce and bring to a boil again.
Add the sorrel, chervil, and Swiss chard, then cover the pot and remove it from heat.
Let it steep for 15 minutes, then strain the broth through a fine sieve.
Carefully degrease the broth and serve warm.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Young chicken
- Gives the broth its main body and savory meaty flavor as it simmers.
- Carrot
- Adds subtle sweetness and aroma to the broth.
- Turnip
- Contributes mild sweetness and a gentle vegetable aroma to the broth.
- Lettuce
- Adds fresh, delicate vegetal flavor when briefly boiled in the broth.
- Sorrel
- Adds bright acidity that lifts the broth's flavor.
The step that matters
Carefully degrease the broth. Fat rises and collects on the surface as the broth cools and simmers. Skimming it off gently keeps the broth clear and prevents a greasy mouthfeel, while disturbing the surface can re-emulsify fat into the liquid.

Fit is the average pairing score against chicken, turnip, lettuce, sorrel, chervil, chard. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
