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 absorb the dressing and bacon fat.
- Bacon
- Adds fat and savory flavor that coats the potatoes.
- White vinegar
- Adds acidity that brightens the salad and balances the fat.
- Onion
- Adds sharp, aromatic flavor to the potatoes.
The step that matters
Mix the potatoes with the bacon and its fat while they are still warm. Warm potatoes absorb fat and seasoning more readily than cold ones, so the flavor distributes evenly. Adding the vinegar after the fat helps it spread without the potatoes drying out.
Swap the onion
How well each one fits the dish's main ingredients (potato, pepper, vinegar, egg):
