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's flavour and moisture.
- Trench dressing or cooked dressing
- Supplies moisture and tang that coat the potato and bind the salad together.
- Hard-boiled egg yolk
- Adds richness and a creamy, crumbly texture to the salad.
- Onion
- Contributes sharp aroma and pungency that mellows as the salad rests.
The step that matters
Mix with the dressing while the potato is still warm. Warm potato absorbs dressing more readily than cold potato, so flavour distributes evenly through the salad instead of sitting on the surface.
Swap the onion
How well each one fits the dish's main ingredients (potato, celery, pepper, egg, parsley, lettuce):
- Carrotfits better
- Spinachfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against potato, celery, pepper, egg, parsley, lettuce. Candidates are from the same food group and used in at least 100 recipes.
