Why it works: Tomato and olive are a kitchen classic. They rank in the top 1% of all ingredient pairs, and cooks put them together in 15,539 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Vegetable Salad, California Style
Ingredients
Directions
Prepare the vegetables
Slice the onion finely.
Peel the cucumbers, cut them in half lengthwise, scoop out the seeds, and slice them.
Peel the tomatoes and slice them into ¼ inch thick slices.
Layer and chill
In a salad bowl, layer the onion, then the tomato, and then the cucumbers, sprinkling each layer with bread crumbs and seasoning with salt, pepper, oil, and vinegar.
Repeat the layering process two more times.
Cover the bowl and set it in a cool place for at least two hours before serving.
Before serving, sprinkle finely chopped parsley and chives on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main juicy body and acidity of the salad.
- Cucumbers
- Add moisture and a crisp, cooling texture to the layers.
- Bread crumbs
- Absorb the dressing and juices, giving the layers body and texture.
- Olive oil
- Adds fat and richness that carries the flavour of the vegetables.
- Vinegar
- Adds sharp acidity that brightens the vegetables and balances the oil.
The step that matters
Resting the layered salad in a cool place. At least two hours lets the salt draw juice from the vegetables and the bread crumbs soak up the dressing, so the flavours blend and the layers hold together.
