Why it works: Parsley and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Potato Salad
Ingredients
Directions
Cook the potatoes
Cook the potatoes with their jackets on until tender.
Peel and cut them while still warm.
Dress and chill
In a salad bowl, combine the potatoes with a little hot water or broth.
Season with salt, pepper, and for every tablespoon of vinegar, add four tablespoons of olive oil.
Add any optional ingredients like onion, parsley, chives, or celery and toss gently.
Chill in the refrigerator before serving.
Serve
Serve in individual lettuce leaves or a salad bowl lined with lettuce, garnished with a spoonful of boiled dressing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Waxy yellow potatoes
- Hold their shape when cut and absorb dressing well without turning mushy.
- Vinegar
- Adds acidity that brightens the flavor and balances the richness of the oil.
- Olive oil
- Adds fat and carries flavor, coating the potato pieces for a smooth mouthfeel.
The step that matters
Dress the potatoes while still warm. Warm potatoes are porous and absorb the vinegar, oil and seasoning far better than cold ones, so the flavor penetrates instead of sitting on the surface. Cutting and dressing them while warm gives a more evenly seasoned salad.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (potato, pepper, vinegar, olive, parsley, chive, celery):
- Mustardfits better
- Shallotfits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against potato, pepper, vinegar, olive, parsley, chive, celery. Candidates are from the same food group and used in at least 100 recipes.
