Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Watercress
- Provides peppery flavor and crisp leafy body to the salad.
- Lettuce
- Forms the crisp, mild bulk of the salad.
- Olive oil
- Coats the leaves, adding fat, silkiness and mouthfeel.
- Vinegar
- Adds acidity that brightens the flavor of the greens and oil.
The step that matters
Toss gently to coat the greens evenly. Delicate leaves bruise and wilt when handled roughly, and dressing added unevenly leaves some leaves greasy and others bare. Gentle tossing keeps leaves intact and coats them lightly with the oil and vinegar.
