Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold boiled potatoes
- Form the bulk of the salad, providing starchy body that holds the dressing.
- Salad dressing
- Adds moisture and richness, coating the potato cubes and binding the salad together.
- Minced onion
- Adds sharp, aromatic flavour that cuts through the richness of the dressing.
- Hard boiled eggs
- Add soft, creamy texture and extra richness to the salad.
The step that matters
Moisten with salad dressing and mix lightly. Cold potatoes can break apart when stirred vigorously, leaving a mushy salad. Gentle folding keeps the cubes intact while coating them evenly with dressing.
Swap the onion
