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 ↓
Potato Salad
Ingredients
Directions
Prepare
Cut cold boiled potatoes into dice.
Use half as much diced celery as potatoes.
Add a little chopped parsley and a few drops of onion juice.
To extract onion juice, rub an onion over a grater, then press tightly to release the juice.
Dress and serve
Mix the salad lightly.
Just before serving, marinate with boiled dressing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold boiled potatoes
- Form the bulk and body of the salad, holding their diced shape when mixed gently.
- Diced celery
- Adds a crisp, fresh crunch that contrasts with the soft potatoes.
- Boiled dressing
- Moistens the salad and adds richness and a tangy flavour that binds the pieces together.
- Onion juice
- Adds a sharp, aromatic bite that lifts the flavour of the potatoes and dressing.
The step that matters
Marinate with the boiled dressing just before serving. Cut potatoes are porous and soak up liquid over time. If dressed too early they absorb the dressing unevenly, becoming soft and watery, so adding it shortly before serving keeps the texture firmer and the flavour fresh.
Swap the onion

- Onionthe original
Fit is the average pairing score against potato, celery, parsley. Candidates are from the same food group and used in at least 100 recipes.
