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 soak up the dressing.
- Bacon
- Adds fat and savoury, smoky flavour to the dressing.
- Vinegar
- Adds acidity that gives the salad its tangy flavour.
- Sugar
- Adds sweetness that balances the sharpness of the vinegar.
The step that matters
Pour the hot mixture over the potatoes and onion. Warm potatoes absorb the vinegar and seasoning more readily than cold ones. Adding the dressing while it is still hot lets the flavour penetrate the slices instead of sitting on the surface.
Swap the onion
How well each one fits the dish's main ingredients (potato, sugar, vinegar, pepper, olive, mustard, flour):
