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, absorbing the dressing while keeping their shape.
- Bacon
- Adds savory fat and browned flavor that carries into the dressing.
- Cider vinegar
- Provides acidity that brightens the salad and balances the richness of the bacon fat.
- Onion
- Adds sharp, aromatic flavor that mellows as it sits in the dressing.
The step that matters
Pour the bacon mixture over the potatoes while it is still warm. Warm potatoes absorb the vinegar and bacon fat more readily than cold ones, so the flavor penetrates the slices instead of sitting on the surface. Mixing gently keeps the slices from breaking apart.
Swap the potato
How well each one fits the dish's main ingredients (pepper, onion, cider, vinegar):
- Mustardfits better
- Capsicumfits better
- Cabbagefits better
- Potatothe original
Fit is the average pairing score against pepper, onion, cider, vinegar. Candidates are from the same food group and used in at least 100 recipes.
