Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Watercress
Provides the leafy, peppery base of the salad.
Lettuce
Adds crisp leaves that give the salad its body.
Vinegar
Adds acidity that brightens the dressing and balances the oil.
Oil
Carries flavor and gives the dressing a smooth, coating texture.

The step that matters

Drying the greens before dressing. Water left on the leaves dilutes the dressing so it slides off instead of clinging. Thorough drying helps the oil and vinegar coat the leaves evenly.

Swap the lettuce

How well each one fits the dish's main ingredients (watercress, vinegar, pepper):

  1. Horseradishfits better
