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 ↓
Lettuce Salad
Ingredients
Directions
Prepare the lettuce
Remove the outer leaves from the lettuces and discard them.
Separate the remaining leaves, cut them in half, and wash thoroughly.
Chop the lettuce and place it in a bowl.
Dress and serve
Sprinkle with salt and pepper, then add oil and vinegar.
Gently toss the salad with a spoon and fork until well mixed.
Garnish with sliced hard-boiled eggs and nasturtium flowers for decoration.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuces
- Forms the leafy base and provides the crisp texture of the salad.
- Oil
- Coats the leaves with fat, giving a smooth mouthfeel and carrying flavour.
- Vinegar
- Adds acidity that brightens the dressing and balances the oil.
- Hard-boiled eggs
- Add richness and substance as a garnish.
The step that matters
Gently toss the salad. Lettuce leaves bruise and wilt easily when handled roughly. Tossing gently with a spoon and fork coats the leaves evenly with dressing while keeping them crisp and intact.
Swap the lettuce
How well each one fits the dish's main ingredients (pepper, vinegar, egg):
- Capsicumfits better
- Mustardfits better
