Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raw eggs
- Bind the dressing and help it thicken and set as it cooks.
- Hard-boiled egg yolks
- Mash into a rich, creamy base that gives the dressing body.
- Flour
- Thickens the dressing so it coats the potatoes instead of running off.
- Melted butter
- Adds fat for richness and a smooth, silky mouthfeel.
- Vinegar
- Adds acidity that brightens the dressing and balances the richness.
- Mixed mustard
- Adds sharp flavor and helps emulsify the dressing.
