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 ↓
Potato Salad
Ingredients
Directions
Prepare the potatoes
Boil the potatoes until tender, then slice them.
Make the salad
Mix the hot potatoes with ham, onion, celery, salt, and cayenne pepper.
Add 3 tablespoons of vinegar to the mixture while it's still hot.
Make the dressing and serve
In a separate bowl, cream the hard boiled eggs with mustard.
Gradually add olive oil and the remaining vinegar to the egg mixture.
Pour the dressing over the potato salad before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the salad and hold their shape once boiled and sliced.
- Vinegar
- Adds acidity that brightens the flavour and seasons the potatoes while they are still hot.
- Hard boiled eggs
- Creamed into the dressing, giving it body and richness.
- Olive oil
- Adds fat that emulsifies into the egg mixture, giving the dressing a smooth, rich texture.
- Ham
- Contributes savoury, salty flavour and meatiness to the salad.
The step that matters
Add the vinegar while the potatoes are hot. Hot potatoes are porous and absorb vinegar and seasoning readily, so adding vinegar while they are still warm flavours them throughout. Once cooled, they absorb far less.
Swap the potato
How well each one fits the dish's main ingredients (vinegar, ham, egg, celery, olive, pepper, mustard):
- Capsicumfits better
- Lettucefits better
- Horseradishfits better
- Potatothe original
Fit is the average pairing score against vinegar, ham, egg, celery, olive, pepper, mustard. Candidates are from the same food group and used in at least 100 recipes.
