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 of the salad, with sliced texture that holds up to dressing.
- Raw onions
- Add sharp, pungent flavour that seasons the potatoes.
- Sweet oil
- Adds fat and mouthfeel, carrying flavour through the salad.
- Vinegar
- Adds acidity that brightens the flavour and balances the oil.
The step that matters
Mix carefully to avoid breaking the potato slices. Cold potato slices are fragile. Rough stirring breaks them into mush and releases starch, which makes the salad pasty instead of holding distinct slices.
Swap the potato
How well each one fits the dish's main ingredients (onion, pepper, vinegar):
- Capsicumfits better
- Mustardfits better
- Cabbagefits better
- Potatothe original
Fit is the average pairing score against onion, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
