Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sardines
- Provide the main fish flavour and a tender, flaky texture in the salad.
- Oil
- Adds richness and moisture, coating the other ingredients and carrying flavour.
- Vinegar
- Adds acidity that brightens the dressing and balances the oil and fish.
- Potato
- Adds body and a soft, starchy texture that soaks up some of the dressing.
- Beet
- Adds earthy sweetness and a deep colour to the salad.
The step that matters
Pour the dressing over the salad. Oil and vinegar separate unless well mixed, so whisk them thoroughly before pouring. Dressing too early can make the potato and beet soggy, so add it just before serving.
Swap the onion
