Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bread crumbs
- Absorb the dressing and vinegar, soaking up liquid so the layers hold together.
- Olive oil
- Adds fat and richness, carrying flavour through the layers.
- Vinegar
- Adds acidity that brightens the vegetables and balances the oil.
- Tomatoes
- Supply juice and acidity that moisten the breadcrumbs during chilling.
- Cucumbers
- Add crisp texture and fresh moisture to the layers.
- White sweet onion
- Adds sharp aroma and bite that mellows during chilling.
The step that matters
Refrigerate for at least two hours. Chilling lets the salt, vinegar and oil draw flavour into the vegetables and softens the breadcrumbs, so the layers meld. Serving too soon leaves the salad dry and sharp.
Swap the onion
