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
- Lettuce
- Forms the bulk of the salad and provides its crisp, leafy texture.
- Oil
- Coats the leaves, adding a silky mouthfeel and carrying flavour.
- Vinegar
- Adds acidity that brightens the dressing and balances the oil.
- Chopped herbs
- Contribute aroma and fresh flavour to the dressing.
The step that matters
Add vinegar last and toss just before serving. Acid wilts and softens lettuce leaves over time, so adding vinegar at the end and serving immediately keeps the leaves crisp and the salad fresh.
Swap the lettuce
How well each one fits the dish's main ingredients (pepper, vinegar):
- Capsicumfits better
- Mustardfits better
- Cabbagefits better
- Lettucethe original
Fit is the average pairing score against pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
