Why it works: Olive and lettuce match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 2,580 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
French Dressing
Ingredients
Directions
Make the dressing
In a bowl, combine vinegar, olive oil, coarse sea salt, white pepper, and sauce.
Prepare the lettuce
Wash the lettuce leaves in very cold water and drain in a basket.
Chill the drained lettuce on ice until serving.
Tear the lettuce into pieces using a fork and spoon, and place it in a salad bowl just before serving.
Serve
Do not let the dressed salad sit before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Olive oil
- Forms the body of the dressing and carries flavour, coating the leaves with richness.
- Vinegar
- Adds acidity that sharpens the dressing and balances the oil.
- Lettuce
- Provides the crisp leaves that the dressing coats and holds.
The step that matters
Dress the salad just before serving. Vinegar and salt draw water out of lettuce leaves, so dressing them early makes the greens limp and soggy. Adding dressing at the last moment keeps them crisp.
Swap the white pepper
How well each one fits the dish's main ingredients (vinegar, olive, sauce, lettuce):
- Capersfits better
- Tarragonfits better
- Garlicfits better
- White pepperthe original
Fit is the average pairing score against vinegar, olive, sauce, lettuce. Candidates are from the same food group and used in at least 100 recipes.
