Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body and juicy moisture of the salad.
- Cucumber
- Adds crisp texture and a cool, fresh bulk to the salad.
- Oil
- Adds fat that carries flavour and gives the dressing a silky mouthfeel.
- Vinegar
- Adds acidity that brightens the vegetables and balances the oil.
- Lettuce
- Forms a crisp, leafy base and adds a light, fresh crunch on top.
The step that matters
Chill the tomatoes until cold. Scalding loosens the skin so it peels off cleanly, and chilling firms the flesh so the segments hold their shape instead of going soft and watery in the dressing.
Swap the onion
