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 ↓
Potato Salad, Hot
Ingredients
Directions
Prepare
Peel and boil the potatoes until done, then slice them thin while hot.
Peel and chop the onions into small bits, then mix with the sliced potatoes.
Cut the bacon into small bits and fry until light brown.
Make the gravy and serve

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 warm sour gravy as they are sliced hot.
- Onions
- Add sharp, pungent flavor that balances the richness of the bacon and gravy.
- Bacon
- Supplies fat and smoky flavor, and its grease forms the base of the dressing.
- Vinegar
- Adds acidity that gives the gravy its sour taste and cuts through the fat.
The step that matters
Pour the gravy over the potatoes while everything is still hot. Potatoes sliced while hot and dressed while warm absorb the fat and vinegar evenly. Once they cool, their starch firms up and they stop taking in the dressing, leaving it greasy on the surface.
Swap the potato
How well each one fits the dish's main ingredients (onion, vinegar):
- Mustardfits better
- Cucumberfits 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.
