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):
- Horseradishfits better
- Capsicumfits better
