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 ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Egg and vinegar barely smell alike, yet cooks put them together in 12,922 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuce
- Forms the crisp bulk of the salad and wilts quickly as it loses water.
- Hard boiled egg
- Adds the chopped white and minced yolk for texture and richness.
- Vinegar
- Adds sharp acidity that brightens the leaves and balances the egg.
The step that matters
Pick the lettuce just before serving. Leaves lose their crispness as they lose moisture after picking. Picking early and holding them lets them wilt, so the salad turns limp and soggy before it reaches the table.
Swap the lettuce
How well each one fits the dish's main ingredients (egg, vinegar, pepper):
- Capsicumfits better
- Mustardfits better
- Cucumberfits better
- Lettucethe original
Fit is the average pairing score against egg, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
