Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Forms the crisp, cool, watery base of the salad.
- Tomatoes
- Add moisture and a soft, juicy texture to the topping.
- Watercress
- Adds a peppery, fresh aroma and flavour to the tomato mixture.
- Lemon juice
- Adds acidity that brightens the flavour of the salad.
- Salad oil
- Adds fat that carries flavour and gives a smooth mouthfeel.
The step that matters
Drying the cucumbers after soaking. Cucumber halves hold water from soaking. If they stay wet, the dressing and topping thin out and slide off. Drying them well lets the topping and oil cling to the surface.
Swap the onion
How well each one fits the dish's main ingredients (cucumber, tomato, watercress, pepper, lemon, lettuce):
- Spinachfits better
- Broccolifits better
- Beetrootfits better
- Onionthe original
