Why it works: Pepper and lettuce 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 leaves
- Provide the crisp, cold base that the dressing coats and carries.
- Oil
- Adds fat that coats the leaves and carries flavor across the salad.
- Vinegar
- Adds acidity that sharpens the dressing and balances the richness of the oil.
The step that matters
Pour in oil and stir until combined. Oil and vinegar do not mix on their own. Stirring breaks the oil into tiny droplets that stay suspended only briefly, so the dressing separates again. Toss it over the lettuce soon after mixing.
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.
