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

What each ingredient does

Eggs
Beaten eggs thicken the dressing and give it a smooth, creamy body.
Sour cream
Provides the creamy base and rich moisture of the dressing.
Vinegar
Adds acidity that brightens the dressing and balances its richness.
Sugar
Sweetens the dressing to offset the vinegar's sharpness.
Potatoes
Form the bulk of the salad and absorb the dressing's flavour.

The step that matters

Beat in the eggs until smooth. Eggs thicken when gently heated, so adding them to a cold, acidic dressing without thorough beating can leave lumps or a loose texture. Beating them smooth distributes the proteins evenly for a uniform, creamy dressing.

Swap the potato

How well each one fits the dish's main ingredients (cream, vinegar, sugar, mustard, egg, pepper, celery):
