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 provide a soft, starchy texture.
- French dressing
- Adds moisture and tangy flavour that coats the potato pieces.
- Onion juice
- Adds a sharp, savoury aroma that lifts the flavour of the potatoes.
The step that matters
Toss gently to combine. Cooked potato pieces are fragile. Rough or prolonged stirring breaks their edges and releases starch, leaving the salad mushy instead of holding distinct pieces coated in dressing.
