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 ↓
Potato Salad
Ingredients

Dress and serve

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.
- Vinegar
- Adds sharp acidity that balances the fat and brightens the flavour.
- Salad oil
- Carries fat-soluble flavour and gives the dressing a smooth, rich mouthfeel.
- Smoked ham
- Browning adds savoury, smoky flavour that carries through the salad.
The step that matters
Toss the hot dressing into the potatoes. Potatoes absorb warm liquid best while still hot, so pouring the heated dressing over them and tossing gently lets them soak up the vinegar and oil evenly. Rough handling can break the slices apart.
Swap the potato
How well each one fits the dish's main ingredients (ham, vinegar, onion):
- Mustardfits better
- Cucumberfits about as well
- Shallotfits about as well
- Potatothe original
Fit is the average pairing score against ham, vinegar, onion. Candidates are from the same food group and used in at least 100 recipes.
