Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Potato Salad
Ingredients
Directions
Make the salad
In a large bowl, combine the potatoes, salt, and pepper.
Add the oil and mix thoroughly.
Stir in the vinegar and optional onion juice or chives.
Arrange the mixture in a mound on a serving plate.
Prepare the garnish
Chop the whites and yolks of the hard boiled eggs separately.
Chop the beets finely, mix with 1 tablespoon vinegar, and let stand for 15 minutes.
Garnish and serve
Garnish the mound with the chopped egg whites, beets, and yolks.
Use parsley to decorate the base and divide the beets from the eggs.

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 absorb the dressing.
- Oil
- Adds fat and coats the potatoes, giving a richer mouthfeel.
- Vinegar
- Adds acidity that brightens the flavour and balances the fat.
- Eggs
- Add richness and contrasting texture as a chopped garnish.
- Beets
- Add colour and a mildly sweet, earthy flavour.
The step that matters
Letting the chopped beets stand with vinegar. Vinegar softens the beets' earthy taste and sets their colour, while keeping them separate from the other garnishes stops the strong red colour from staining them.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (potato, pepper, vinegar, chive, egg, parsley):
- Shallotfits better
- Spinachfits better
- Mustardfits better
- Onionthe original
Fit is the average pairing score against potato, pepper, vinegar, chive, egg, parsley. Candidates are from the same food group and used in at least 100 recipes.
