Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuce
- Forms the bulk of the salad and provides crisp, watery texture.
- Hard-boiled eggs
- Add richness and body to the salad.
- Vinegar
- Adds acidity that brightens the dressing and balances the oil.
- Oil
- Adds fat that carries flavor and gives the dressing a smooth mouthfeel.
- Prepared mustard
- Adds sharp flavor and helps emulsify the oil and vinegar.
- White sugar
- Softens the sharpness of the vinegar and mustard.
The step that matters
Mix well. Oil and vinegar separate unless thoroughly whisked or tossed, and the mustard helps bind them. Mixing just before serving keeps the greens crisp and the dressing evenly distributed.
Swap the radish
How well each one fits the dish's main ingredients (lettuce, mustard, watercress, cucumber, egg, sugar, pepper):
- Horseradishfits better
- Beetrootfits better
- Chivefits better
