Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the salad and hold their shape while absorbing some of the dressing.
- Vinegar
- Adds acidity that brightens the dressing and balances the sweetness and richness.
- Sweet cream
- Adds richness and a smooth, creamy texture to the dressing.
- Mustard
- Adds sharp, pungent flavour and helps emulsify the dressing.
- Hard boiled eggs
- Add richness and a soft, creamy texture to the salad.
The step that matters
Let the dressing cool before adding the cream. Cream added to a hot, acidic mixture can curdle or split, leaving the dressing grainy. Cooling it first keeps the cream smooth.
Swap the onion
