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 dressing as they cool.
Vinegar
Adds acidity that brightens the flavour and moistens the sliced potato.
Melted butter
Adds fat and richness, coating the potatoes for a smoother mouthfeel.
Onion
Contributes sharp, aromatic flavour that cuts through the richness.

The step that matters

Slice the potatoes while hot. Warm potatoes have open, loosened starch that soaks up the vinegar and butter evenly. Once cold they firm up and resist seasoning, so dressing them later leaves them patchy.

Swap the potato

How well each one fits the dish's main ingredients (pepper, onion, vinegar, butter):

  4. Chivefits about as well

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