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 the dressing as tender pieces.
- Eggs
- Yolks enrich the dressing and add a creamy, smooth body.
- Vinegar
- Adds acidity that sharpens the flavour of the dressing.
- Cream
- Adds fat and moisture, making the dressing rich and smooth.
- Onions
- Add sharp, aromatic flavour to the seasoned potatoes.
The step that matters
Heat the vinegar in a saucepan. Heating vinegar before combining it with the eggs and cream changes how the dressing blends and tastes. Heat should be gentle enough that the eggs do not scramble or curdle when the mixture is combined, which keeps the dressing smooth.
Swap the onion
How well each one fits the dish's main ingredients (potato, pepper, celery, egg, butter, mustard, vinegar):
