Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

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 as they are sliced while hot.
- Onions
- Add sharp, savory flavor that balances the richness of the bacon.
- Breakfast bacon
- Supplies fat and smoky flavor, and its grease forms the base of the dressing.
- Vinegar
- Adds acidity that brightens the salad and cuts the richness of the bacon fat.
The step that matters
Slice the boiled potatoes thin while hot. Warm potatoes take in dressing more readily than cold ones, so the flavor distributes evenly. Cooling them first makes the slices firmer and less absorbent.
Swap the potato
How well each one fits the dish's main ingredients (onion, vinegar):
- Mustardfits better
- Cucumberfits better
- Radishfits better
- Potatothe original
Fit is the average pairing score against onion, vinegar. Candidates are from the same food group and used in at least 100 recipes.
