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 hot dressing, becoming tender and flavorful.
- Onion
- Adds sharp aroma and savory flavor when softened in fat.
- Lard
- Fat that carries the onion flavor and adds richness to the salad.
- Vinegar
- Provides acidity that gives the salad its tangy, sharp flavor.
The step that matters
Pour the hot mixture over the potatoes. Hot dressing soaks into sliced potatoes while they are still warm, so they absorb flavor evenly. Cooled potatoes stay bland and dry on the surface.
Swap the potato
How well each one fits the dish's main ingredients (pepper, onion, vinegar):
- Capsicumfits better
- Mustardfits better

- Potatothe original
Fit is the average pairing score against pepper, onion, vinegar. Candidates are from the same food group and used in at least 100 recipes.
