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, absorbing the dressing while staying tender.
- Bacon
- Adds fat and savory, browned flavor that carries through the salad.
- White vinegar
- Adds acidity that brightens the salad and balances the fat from the bacon.
- Onion
- Adds sharp, aromatic bite that complements the potatoes and bacon.
The step that matters
Slice the potatoes while hot. Warm potatoes take in dressing and seasoning more readily than cold ones, so the salad absorbs flavor evenly. Cutting them while hot helps them keep their shape without crumbling.
Swap the onion
How well each one fits the dish's main ingredients (potato, pepper, vinegar, egg):
- Capsicumfits better
- Mustardfits better

- Onionthe original
Fit is the average pairing score against potato, pepper, vinegar, egg. Candidates are from the same food group and used in at least 100 recipes.
