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 absorb the dressing's flavour as they are mixed in.
- Raw egg yolk
- Emulsifies the oil and vinegar so the dressing becomes thick and creamy.
- Hard-boiled eggs
- Add richness and body to the dressing through their cooked yolks.
- Oil
- Provides fat that gives the dressing a smooth, rich texture.
- Vinegar
- Adds acidity that brightens the dressing and balances the richness of the oil and yolks.
- Celery
- Adds crunch and a fresh, slightly savoury flavour to the salad.
The step that matters
Mixing the raw egg yolk into the dressing. The raw yolk must be thoroughly combined with the yolks and oil so it emulsifies properly; if the oil is added too fast or not blended well, the dressing can separate and turn greasy rather than creamy.
