Why it works: Lettuce and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 4,037 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White lettuce
- Forms the crisp, leafy body of the salad.
- Sweet oil
- Adds fat and a smooth mouthfeel that coats the leaves.
- Vinegar
- Adds acidity that brightens the dressing and balances the oil.
- Coarse sea salt
- Seasons the leaves and draws out flavor from the dressing.
The step that matters
Drain the lettuce thoroughly. Water left on the leaves dilutes the dressing so it slides off instead of clinging. Dry leaves let the oil and vinegar coat them evenly and keep the salad crisp when served.
Swap the lettuce
