Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spanish onions
- Form the salad's main body and provide a sharp, savoury flavour once cooked.
- Good cream
- Adds richness and fat to the dressing, softening the sharpness of the vinegar.
- Vinegar
- Adds acidity that brightens the dressing and balances the cream.
- Mustard
- Adds a sharp, pungent flavour and helps the cream and vinegar hold together.
- Beetroot
- Adds earthy sweetness and colour to the salad.
The step that matters
Dressing just before serving. Vinegar and salt draw liquid out of the onions and beetroot over time, so the salad turns watery and limp if dressed too early. Pouring the dressing on just before serving keeps the vegetables crisp.
Swap the onion
How well each one fits the dish's main ingredients (cream, vinegar, mustard, beetroot):
- Horseradishfits better
- Lettucefits better
