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 ↓
Salad-Making
Ingredients
Directions
Prepare the lettuce
Place lettuce in the refrigerator in a covered container.
Cut off the stem and separate the leaves, discarding the outer ones.
Soak the leaves in cold water for at least 15 minutes.
Wash the leaves gently and check for insects.
Shake or swing the leaves in a basket to dry them.
Wipe the leaves with a soft cloth to remove excess moisture.
Dress and serve
Dress the salad with salt, pepper, oil, and vinegar just before serving.

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, watery base that carries the dressing.
- Oil
- Coats the leaves and carries flavour across the salad.
- Vinegar
- Adds acidity that brightens the dressing and balances the oil.
The step that matters
Dry the leaves thoroughly. Excess water dilutes the dressing and stops oil from clinging to the leaf surfaces, so the salad turns limp and watery. Drying before dressing keeps the leaves crisp and lets the dressing coat them evenly.
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.
