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 absorb the dressing while hot.
- Egg
- Beaten until stiff, it adds body and richness to the dressing.
- Vinegar
- Adds the sharp acidity that balances the butter and sugar.
- Melted butter
- Adds fat and richness to the dressing.
- Onion
- Adds sharp, aromatic flavour to the seasoned potatoes.
- Sugar
- Sweetens the vinegar to balance its sharpness.
The step that matters
Pour the dressing over the hot potatoes and toss lightly. Warm potatoes absorb the dressing far better than cold ones, so the flavour penetrates. Tossing lightly avoids breaking the potatoes into a mush.
Swap the onion
How well each one fits the dish's main ingredients (potato, egg, vinegar, butter, pepper, celery, parsley):
