Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard cooked egg
- Provides the white shell for holding the filling and the yolk for the mixture.
- Chicken
- Adds savory protein bulk to the mashed yolk filling.
- Olive oil or butter
- Adds fat that makes the mashed yolk filling smooth and rich.
- Mustard
- Adds sharp, tangy flavor that cuts the richness of the yolk.
The step that matters
Mashing the yolk with the fat. Mash the yolk thoroughly before adding the other ingredients so it blends evenly. Lumps of dry yolk stay grainy, while adding the oil or butter gradually helps it emulsify into a smooth, spreadable filling.
Swap the lettuce
How well each one fits the dish's main ingredients (egg, chicken, vinegar, mustard, olive):

- Cucumberfits about as well
- Broccolifits about as well
Fit is the average pairing score against egg, chicken, vinegar, mustard, olive. Candidates are from the same food group and used in at least 100 recipes.
