Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Provide the crisp, watery body of the salad.
- Tomatoes
- Add juiciness and a mild acidic sweetness to the topping.
- Lemon juice
- Adds acidity that brightens the flavour of the salad.
- Salad dressing
- Adds fat and seasoning that coat the vegetables and carry flavour.
The step that matters
Drain and dry the cucumbers. Cucumbers hold a lot of water, and any left on the surface will dilute the dressing and make the salad soggy. Drying them well keeps the topping in place and the flavours concentrated.
Swap the onion
How well each one fits the dish's main ingredients (cucumber, tomato, watercress, pepper, lettuce, lemon):
- Spinachfits better
- Broccolifits better
