Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard boiled eggs
- Form the main body and bulk of the salad.
- Mayonnaise
- Adds moisture and creaminess that binds the chopped eggs together.
- Prepared mustard
- Adds a sharp, tangy flavour that cuts the richness of the eggs and mayonnaise.
- Grated red onion
- Adds sharpness and aroma to the salad.
The step that matters
Chilling the salad. Chilling for at least three hours lets the flavours meld and firms the mayonnaise so the salad holds together and tastes less sharp. Serving it warm or too soon leaves the seasoning harsh and the texture loose.
Swap the onion
How well each one fits the dish's main ingredients (egg, mustard, milk):
- Horseradishfits better
- Asparagusfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against egg, mustard, milk. Candidates are from the same food group and used in at least 100 recipes.
