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

What each ingredient does

Cold boiled potatoes
Form the bulk of the salad and hold the dressing in their starchy surfaces.
Olive oil
Adds fat and richness, and emulsifies with the mustard to make the sauce creamy.
Mustard
Acts as an emulsifier, helping oil and vinegar stay blended into a smooth sauce.
Vinegar
Adds acidity that brightens the flavour and balances the richness of the oil.
Onions
Contribute sharp, aromatic flavour that cuts through the potatoes and oil.

The step that matters

Toss the sauce into the warm or cool potatoes gently. Vigorous tossing breaks down the sliced potatoes and can make the salad mushy. Gentle folding coats each slice evenly with the emulsified dressing while keeping its shape.

Swap the onion

How well each one fits the dish's main ingredients (potato, parsley, mustard, pepper, vinegar, olive):

  1. Broccolifits better
  2. Lettucefits better
  3. Horseradishfits better
