Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold boiled potatoes
- Makes up the bulk and body of the salad, holding the dressing.
- Vinegar
- Adds acidity that brightens the flavour and balances the richness.
- Browned butter
- Adds fat and a nutty, toasted aroma that coats the potato pieces.
- Onion
- Adds sharp aroma and a pungent bite that cuts through the fat.
The step that matters
Mix everything together thoroughly. Vinegar and browned butter must be spread evenly through the chopped potatoes and onion. Uneven mixing leaves some pieces sharp or acidic and others bland or greasy.
