Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the salad and hold their shape when cut into pieces.
- Eggs
- Their proteins set as they heat, thickening the vinegar mixture into a dressing.
- Vinegar
- Adds the sharp acidity that defines the dressing's tang.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
- Butter
- Adds fat and richness that coat the potatoes and soften the flavor.
The step that matters
Boil the eggs, vinegar, and sugar until thick. Egg proteins set as they heat and thicken the mixture, but if it overheats the eggs can curdle and turn grainy. Stir steadily and remove it once it has thickened.
Swap the celery
How well each one fits the dish's main ingredients (potato, egg, vinegar, sugar, butter, onion, pepper):
- Garlicfits better
- Parsleyfits better
- Tarragonfits better
- Celerythe original
Fit is the average pairing score against potato, egg, vinegar, sugar, butter, onion, pepper. Candidates are from the same food group and used in at least 100 recipes.
