Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Hard-boiled eggs: Provide the creamy, bulky base of the salad.
Boiled potatoes: Add body and a smooth, soft texture once sieved.
Olive oil: Adds fat and richness, carrying flavour and giving a silky mouthfeel.
Vinegar: Adds acidity that brightens the dressing and balances the rich fat.
Mustard: Adds sharpness and helps the oil and vinegar stay emulsified.
Anchovy sauce: Contributes savoury, umami depth to the dressing.

The step that matters

Mix in the olive oil and vinegar gradually. Adding oil slowly while mixing lets the mustard help form a stable emulsion, so the dressing stays smooth instead of separating into greasy pools.
