Potato Salad
Ingredients
Directions
Prepare
Slice the hot boiled potatoes into pieces.
Add chopped onion and parsley to the potatoes.
Pour a generous amount of plain salad dressing over the mixture.
If the salad appears too dry, add a little hot water or soup stock.
Chill and serve
Toss the salad gently to avoid breaking the potato slices.
Chill the salad on ice until cold.
Serve on small plates with a lettuce leaf and two tablespoons of potato salad for each person.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Boiled potatoes
- Provides the bulk and starchy body that holds the salad together.
- Plain salad dressing
- Adds moisture, fat and tang that coat the potato pieces.
- Chopped onion
- Adds sharp aroma and a bit of bite.
The step that matters
Toss the salad gently. Cooked potato slices are fragile and break easily when stirred roughly, which leaves the salad mushy and broken-looking. Gentle folding keeps the pieces intact so the salad keeps its texture.
Swap the onion
How well each one fits the dish's main ingredients (potato, parsley, lettuce):
- Beetrootfits better
- Chivefits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against potato, parsley, lettuce. Candidates are from the same food group and used in at least 100 recipes.
