Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Watercress
- Provides the crisp, peppery leafy base of the salad.
- Olives
- Add salty, briny flavour that contrasts with the sharp dressing.
- Sour apples
- Add tart, crisp bite that balances the oil and salt.
- Oil
- Carries flavour and coats the leaves with a smooth richness.
- Vinegar
- Adds acidity that sharpens the dressing and lifts the other flavours.
The step that matters
Dry the watercress before dressing. Wet leaves dilute the dressing and make it slide off, so the oil and vinegar do not coat them evenly. Wiping the leaves dry after soaking keeps the salad crisp and the dressing clinging.
Swap the apple
How well each one fits the dish's main ingredients (watercress, parsley, olive, vinegar, pepper, egg):
- Lemonfits better
