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 warm vinegar dressing as it sits.
- Onion
- Adds sharp, pungent flavor that mellows slightly during chilling.
- Vinegar
- Provides acidity that brightens the dressing and balances the richness of the pork fat.
- Salt pork fat
- Adds savory richness and fat that carries flavor through the salad.
The step that matters
Pour the hot mixture over the layered salad. The hot fat and vinegar must be poured while still hot so the potatoes absorb the dressing evenly. Cooling first would leave the dressing pooled and unabsorbed.
Swap the onion
