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 salad base
Boil the potatoes until tender, then let them cool and cut into small bits.
In a bowl, combine the potatoes, celery, mashed eggs, onion, pepper, salt, and sugar.
Make and add the dressing
For the dressing, beat the eggs until light, then mix in the sour cream, vinegar, butter, mustard, pepper, salt, and sugar.
Heat the dressing on the stove, stirring constantly until it comes to a boil, then let it cool.
Pour the cooled dressing over the salad and refrigerate until chilled.
Finish and serve
Before serving, stir in the whipped cream and serve on lettuce or cabbage leaves.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten eggs cook into the dressing, thickening it and giving it body as it heats.
- Sour cream
- Adds tang and creaminess, keeping the dressing moist and smooth.
- Potatoes
- Form the bulk of the salad, holding their shape once cooked and chilled.
- Whipped cream
- Stirred in at the end to lighten the texture and add richness.
- Vinegar
- Adds acidity that balances the richness of the eggs, cream and butter.
The step that matters
Heating the dressing until it boils. Beaten eggs can curdle or scramble if overheated, so stirring constantly keeps the dressing smooth while the egg proteins thicken it evenly.
