Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Watercress leaves
- Provide the crisp, peppery leafy base of the salad.
- Oil
- Carries flavour and gives the dressing a smooth, rich mouthfeel.
- Vinegar
- Adds acidity that brightens the dressing and balances the oil.
- Sour apples
- Add tart crunch and contrast to the bitter greens.
The step that matters
Drying the watercress. Leaves that stay wet dilute the dressing so it slides off instead of clinging, and the salad turns limp. Wiping them dry lets the oil and vinegar coat the leaves evenly.
Swap the apple
How well each one fits the dish's main ingredients (watercress, parsley, olive, vinegar, pepper, egg):
- Lemonfits better
- Limefits better
- Avocadofits better
- Applethe original
Fit is the average pairing score against watercress, parsley, olive, vinegar, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
