Why it works: Lettuce and chervil match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 396 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Lettuce Salads
Ingredients
Directions
Prepare the lettuce
Trim the outer leaves of the lettuce and wash the heads in cold water.
Trim the leaves and drain them on a salad strainer.
Before serving, drain on a napkin without pressing the leaves.
Dress and serve
Place the lettuce in a salad bowl and season with salt, pepper, oil, and vinegar.
Dress the salad just before serving.
For a mustard dressing, mash the yolk of a hard boiled egg in a bowl, dilute with oil and vinegar, add mustard, and season with salt and pepper.
Pour the dressing over the lettuce and mix gently with a wooden spoon and fork.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuce
- Forms the body of the salad; its crisp leaves give the dish its texture.
- Sweet oil
- Carries flavour and coats the leaves, giving a smooth, slippery mouthfeel.
- Vinegar
- Adds acidity that brightens the dressing and balances the richness of the oil.
The step that matters
Drain the leaves without pressing them. Excess water left on the leaves dilutes the dressing and makes it slide off, while pressing bruises the leaves and makes them limp. Gentle draining keeps them crisp enough to hold the dressing.
Swap the mustard
The recipe marks mustard as optional. How well each one fits the dish's main ingredients (lettuce, pepper, vinegar, egg, sugar, cream, chervil):
- Mustardthe original
- Chivefits about as well
- Beetrootfits about as well
- Shallotfits about as well
Fit is the average pairing score against lettuce, pepper, vinegar, egg, sugar, cream, chervil. Candidates are from the same food group and used in at least 100 recipes.
