Ingredients
Directions
In a bowl, mix the lettuce with the oil.

Gently toss the lettuce in the vinegar mixture, ensuring not to drown it in sauce.

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, fresh texture.
- Oil
- Coats the leaves, spreading flavour and giving a smooth mouthfeel.
- White wine vinegar
- Provides the sharp acidity that brightens the dressing.
The step that matters
Tossing the lettuce in the vinegar mixture. Too much liquid wilts the leaves and dilutes the dressing. Light, gentle tossing keeps the leaves crisp and lets the oil and vinegar cling to the surface, so each leaf is lightly seasoned rather than soggy.
Swap the lettuce
How well each one fits the dish's main ingredients (white wine, vinegar, pepper):
- Capsicumfits better
- Shallotfits better
- Mustardfits better
- Lettucethe original
Fit is the average pairing score against white wine, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
