Why it works: Celery and mustard are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 4,169 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Chicken Salad
Ingredients
Directions
Prepare
Steam or boil the chickens until tender, then cut the meat into small pieces using scissors.
Cut the celery into small pieces and sprinkle with 1 teaspoon of salt.
Make the dressing
In a bowl, mash the yolks of the hard-boiled eggs while hot, then mix in the butter, 2 teaspoons of salt, 1 teaspoon of pepper, and 2 teaspoons of mixed mustard.
Gradually stir in the vinegar until well combined.
Assemble and rest
Chop the 4 hard-boiled eggs and mix them with the chicken and celery.
Pour the dressing over the chicken mixture and let it stand for at least 1 hour before serving.
If desired, add 6 chopped cucumber pickles to the salad.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken
- Provides the main protein and meaty bulk that the salad is built around.
- Hard-boiled egg yolks
- Mashed into the dressing, they make it rich and creamy and help bind it.
- Butter
- Adds richness and a smooth, creamy texture to the dressing.
- Vinegar
- Adds acidity that sharpens the flavour and balances the richness of the dressing.
- Celery
- Contributes crisp texture and fresh, mild flavour to the salad.
The step that matters
Mashing the yolks while hot and adding the vinegar gradually. Warm yolks blend more smoothly with butter and mustard into an even emulsion. Adding vinegar slowly lets the dressing thicken evenly rather than separating or turning thin and curdled.
Swap the cucumber
The recipe marks cucumber as optional. How well each one fits the dish's main ingredients (chicken, celery, egg, butter, pepper, mustard, vinegar):
- Capsicumfits better
- Lettucefits about as well
- Chivefits about as well
- Cucumberthe original
Fit is the average pairing score against chicken, celery, egg, butter, pepper, mustard, vinegar. Candidates are from the same food group and used in at least 100 recipes.
