Why it works: Lettuce and vinegar are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 2,370 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

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 and holds the dressing on its leaves.
- Oil
- Coats the leaves, giving them a glossy shine and a smooth mouthfeel.
- Vinegar
- Adds acidity that brightens the flavour of the oil and greens.
The step that matters
Dry the lettuce before dressing. Water on the leaves dilutes the oil and vinegar, so the dressing slides off and the salad tastes watery. Thoroughly dry leaves let the oil cling evenly.
Swap the white pepper
How well each one fits the dish's main ingredients (lettuce, vinegar):
- Tarragonfits better
- Capersfits better
- Dillfits better
- White pepperthe original
Fit is the average pairing score against lettuce, vinegar. Candidates are from the same food group and used in at least 100 recipes.
