Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the body of the salad and soak up the warm dressing.
- Butter
- Adds rich, nutty flavour when browned and carries flavour into the dressing.
- Vinegar
- Adds sharp acidity that balances the richness of the butter and potatoes.
- Onion
- Adds sharp, aromatic flavour that mellows in the warm dressing.
The step that matters
Pour the hot mixture over the salad and stir gently. The potatoes must still be warm so they absorb the hot vinegar dressing well. Stirring gently keeps the thin slices from breaking apart while they coat evenly.
