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 when cooked until tender.
- Egg yolks
- Emulsify with the mustard and vinegar to make a creamy, rich dressing.
- Mustard
- Adds sharp flavour and helps bind the yolks into the dressing.
- Vinegar
- Adds acidity that brightens the dressing and cuts the richness of the yolks.
- Celery
- Adds crunch and a fresh, slightly savoury flavour.
The step that matters
Let the potatoes cool before adding the dressing. Warm potatoes absorb dressing unevenly and can make the salad greasy or soupy. Cooling them first lets them hold their shape and take in the dressing more evenly.
Swap the potato
