Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomato
- Forms the bulk of the salad and provides its fresh, juicy body.
- Onions
- Add sharp, pungent flavour that mellows somewhat after boiling.
- Garlic
- Adds pungent aroma and savoury depth to the salad.
- Olive oil
- Adds fat and smooth richness that carries the flavours.
The step that matters
Drain the boiled onions well. Boiling softens the sharp compounds in onions, but leftover water would dilute the dressing and make the salad watery. Draining thoroughly keeps the texture firm and the flavours concentrated.

- Clovethe original
Fit is the average pairing score against tomato, onion, garlic, pepper, olive. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
