Why it works: Lettuce and olive 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 ↓

Ingredients
Directions
Prepare the lettuce
Remove the outer leaves from the lettuce and pull it apart.
Wash the lettuce thoroughly without running water directly on it to avoid bruising.
Wrap the lettuce and refrigerate for 2 hours before serving.
Make the dressing
In a bowl, mix the olive oil, salt, and pepper.
Add the vinegar and let the mixture stand for 15 minutes.
Before serving, beat the dressing until thick and apply it to the lettuce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuce
- Forms the bulk of the salad and carries the dressing, providing crisp texture.
- Olive oil
- Adds fat and body, coating the leaves and carrying flavor.
- Vinegar
- Adds acidity that brightens the dressing and balances the oil.
The step that matters
Beat the dressing until thick. Oil and vinegar separate unless they are beaten or emulsified together. Beating just before serving keeps the dressing blended so it clings to the leaves instead of pooling at the bottom of the bowl.
Swap the onion
How well each one fits the dish's main ingredients (lettuce, olive, vinegar, pepper):
- Mustardfits better
- Capsicumfits better
- Cucumberfits better
- Onionthe original
Fit is the average pairing score against lettuce, olive, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
