Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Directions
Prepare the potatoes
Boil the potatoes until tender, then cool and peel them.
Cut the potatoes into cubes and place them in a large bowl.
Dress and serve
In a separate bowl, mix vinegar, water, onions, celery, and mayonnaise.
Pour the dressing over the potatoes and gently mix until well combined.
Season with coarse sea salt to taste and serve chilled.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy base that holds its cubed shape and absorbs the dressing.
- Mayonnaise
- Adds fat and creaminess, coating the potatoes and giving the salad its moist texture.
- Vinegar
- Adds acidity that brightens the flavour and balances the richness of the mayonnaise.
- Onions
- Contribute a sharp aroma and savoury bite that cuts through the creamy dressing.
- Celery
- Adds a crisp, fresh crunch that contrasts with the soft potatoes.
The step that matters
Gently mix the dressing into the potatoes. Cooked potato cubes are fragile. Vigorous stirring breaks their surfaces and crushes them into a mush, so folding gently keeps the pieces intact while the dressing coats them evenly.
Swap the celery
How well each one fits the dish's main ingredients (potato, vinegar, onion):
- Garlicfits better
- Dillfits better
- Thymefits about as well
- Celerythe original
Fit is the average pairing score against potato, vinegar, onion. Candidates are from the same food group and used in at least 100 recipes.
