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, holding their shape when sliced thin.
- Eggs
- Add body and richness, with chopped whites and yolks blending into the dressing.
- Sweet cream
- Adds richness and moisture, coating the potatoes and eggs.
- Vinegar
- Adds acidity that brightens the rich cream and balances the flavour.
- Onion
- Adds sharp aroma and bite that mellows during resting.
The step that matters
Add a little vinegar and plenty of sweet cream. Potatoes absorb dressing as they cool, so seasoning and dressing added while the potatoes are still warm will soak in more evenly. Add the vinegar sparingly, since too much acid makes the salad sharp and can thin the cream.
Swap the onion
