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
- Carries flavour and coats the leaves for a smooth mouthfeel.
- Vinegar
- Adds acidity that brightens the dressing and balances the oil.
- Coarse sea salt
- Seasons the dressing and draws out flavour from the leaves.
The step that matters
Dress the lettuce just before serving. Salt and acid draw water out of lettuce leaves, so dressing too early makes them limp and watery. Tossing right before serving keeps the leaves crisp.

Fit is the average pairing score against pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
