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
Ingredients
Directions
Prepare the potatoes
Boil the potatoes with their skins on.
Peel while hot and cut into slices ⅛ inch thick.
Sprinkle salt and pepper over the potatoes.
Add chopped onions.
Make the dressing
Fry the bacon in a skillet until crisp and golden brown.
Add cider vinegar to the bacon and pour over the potato mixture.
Mix and serve
Mix gently with a salad fork to avoid breaking the potatoes.
Serve warm or cold, with Frankfurt sausages arranged around the salad.

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, holding their shape when sliced and gently mixed.
- Bacon
- Adds fat and savory browned flavor, which is carried into the dressing.
- Cider vinegar
- Provides acidity that brightens the salad and balances the richness of the bacon fat.
- Onions
- Add sharp, aromatic flavor that mellows as the salad sits.
- Olive oil
- Adds fat and smoothness to the dressing and carries flavor.
The step that matters
Peel while hot and cut into slices. Warm potatoes absorb the vinegar and seasoning more readily than cold ones. Cutting them gently keeps the slices intact, so they hold their shape during mixing.
Swap the onion
How well each one fits the dish's main ingredients (potato, pepper, cider, vinegar, olive):
