Why it works: Parsley and pepper 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 ↓

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.
- Onions
- Add sharp, savory flavor that mellows as the salad stands.
- Vinegar
- Adds acidity that brightens the dish and balances the oil.
- Oil
- Adds fat and richness, carrying flavor and coating the potatoes.
The step that matters
Allow the salad to stand for an hour before serving. Standing lets the vinegar and oil soak into the warm potato slices, so flavor spreads through the salad rather than sitting on the surface. Potatoes absorb dressing best while still warm, so the dressing should be added before they cool.
Swap the onion
How well each one fits the dish's main ingredients (potato, parsley, pepper, vinegar):
- Carrotfits better
- Capsicumfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against potato, parsley, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
