Why it works: Celery and parsley 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 ↓

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 as they warm.
- Vinegar
- Adds acidity that sharpens the flavour and balances the fat.
- Goose or duck fat or olive oil
- Adds richness and moisture, coating the potatoes and carrying flavour.
The step that matters
Pour the hot mixture over the potatoes and mix lightly. Warm dressing soaks into warm potato slices, so they take on flavour and a glossy coating. Mixing gently keeps the slices from breaking up into mush.
Swap the onion
How well each one fits the dish's main ingredients (potato, celery, parsley, pepper, vinegar, olive):
- Carrotfits better
