Why it works: Sorrel and chervil match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 247 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Chicken Broth a LA Chiffonade
Ingredients
Directions
Prepare the chicken broth
Cut the fowl into small pieces.
In a stewpan, heat 2 oz. of butter and add the chicken pieces, seasoning with salt and pepper. Fry until slightly browned.
Add the stock and bring to a boil. Skim off any foam.
Add a small bunch of parsley, the bouquet garni, and the prepared leeks. Simmer gently for about 2 hours.
Make the chiffonade
Wash the sorrel, chervil, and lettuce, using only the tender leaves. Cut these vegetables into very fine strips.
In another stewpan, combine the vegetables with 1 oz. of butter and stir gently over heat for 10 minutes.
Add some of the broth to the vegetable mixture. Skim. Cook for about 15 minutes.
Strain the remaining broth into the vegetable mixture. Season to taste.
Serve
Place neat pieces of chicken in a tureen.
Pour in the soup.
Serve as hot as possible.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fowl
- Provides the meat and flavour that give the broth its body.
- Butter
- Adds richness and carries flavour when frying the chicken and softening the greens.
- White stock
- Forms the liquid base of the broth.
- Leeks
- Add a mild onion-like sweetness and aroma to the broth.
- Sorrel
- Adds a sharp, lemony acidity to the finished soup.
- Lettuce
- Adds tender body and a mild, fresh vegetable flavour to the chiffonade.
The step that matters
Skimming the broth after boiling. Foam rising during the first boil contains coagulated proteins and impurities that cloud the broth and taste bitter if left in, so removing it keeps the soup clear and clean-flavoured.
Swap the thyme
How well each one fits the dish's main ingredients (butter, leek, parsley, lettuce, sorrel, chervil, pepper):
- Capersfits better
- Tarragonfits better
- Thymethe original
- Marjoramfits less well
Fit is the average pairing score against butter, leek, parsley, lettuce, sorrel, chervil, pepper. Candidates are from the same food group and used in at least 100 recipes.
