Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the vinegar dressing as they cook, giving it a creamy body.
- Vinegar
- Adds acidity that sharpens the flavor and balances the sugar.
- Sugar
- Sweetens the dressing to offset the sharpness of the vinegar.
- Potatoes
- Form the bulk of the salad and absorb the dressing's flavor.
- Onions
- Add sharp, savory aroma and crunch to the salad.
The step that matters
Bring the mixture to a boil. Eggs thicken when heated, but if they get too hot they can scramble into lumps. Stir constantly and heat gently until the dressing thickens, then pour it over the potatoes.

Fit is the average pairing score against onion, potato, pepper, egg, sugar, vinegar, butter. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
