Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the bulk of the salad, soaking up the dressing as they are cut and warm.
- Beets
- Add earthy sweetness and a vivid color to the salad.
- Hard-boiled egg yolks
- Mashed into the dressing, they add richness and a smooth, creamy body.
- Dry mustard
- Adds sharp, pungent flavor that balances the richness of the yolks and butter.
- Melted butter
- Adds fat for richness and helps bind the dressing smoothly.
- Vinegar
- Adds acidity that brightens the dressing and thins it to a creamy consistency.
The step that matters
Adding vinegar to the dressing. Vinegar must be added gradually. Too much thins the mixture and it can split, while too little leaves it stiff and dull. Stopping at a cream-like texture gives a smooth, cohesive dressing that coats the cubes evenly.
Swap the mustard
How well each one fits the dish's main ingredients (potato, egg, butter, vinegar, cream, pepper, parsley):
