Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Potatoes: Cold boiled potatoes add body and bulk, holding their shape in the salad.
Butter: Beaten with vinegar, it coats the vegetables and adds richness and moisture.
Vinegar: Adds acidity that brightens the flavour and balances the butter.
Cucumbers: Provide the crisp, watery texture and fresh flavour that give the salad its character.
