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 and mix with the potatoes.
Cut the bacon into small bits and fry until light brown.
Dress and serve
Remove the bacon and stir the vinegar into the bacon grease to make a sour gravy.
Pour the gravy over the potato and onion mixture and mix lightly.
Serve hot.

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 warm gravy and holding their shape when sliced thin.
- Onions
- Add sharp, pungent flavor that mellows slightly in the warm dressing.
- Bacon
- Supplies fat and smoky flavor, and its drippings become the base of the dressing.
- Vinegar
- Adds acidity that sours the bacon grease into a tangy gravy.
The step that matters
Pour the gravy while the potatoes are still hot. Warm potatoes absorb the vinegar-spiked bacon fat more readily, so the flavor distributes through the slices. Mix lightly so the thin slices do not break apart.
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.
