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 once cooled and cut.
- Egg yolks
- Emulsify the oil and vinegar into a creamy, smooth dressing.
- Salad oil
- Adds richness and moisture to the dressing and coats the potatoes.
- Vinegar
- Adds acidity that brightens the dressing and balances the richness of the oil and yolks.
- Mustard
- Adds sharpness and helps stabilise the emulsified dressing.
The step that matters
Cool the boiled potatoes completely. Warm potatoes absorb dressing unevenly and can turn mushy or greasy, and warm dressing can thin or break. Cooling firms the cut potato so it keeps its shape and takes dressing evenly.
Swap the onion
How well each one fits the dish's main ingredients (potato, celery, egg, mustard, sugar, vinegar):
- Horseradishfits better
- Chivefits better
- Lettucefits better
- Onionthe original
Fit is the average pairing score against potato, celery, egg, mustard, sugar, vinegar. Candidates are from the same food group and used in at least 100 recipes.
