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 bulk of the salad, holding their shape when sliced while hot.
- Onions
- Add sharp, pungent flavour that mellows and sweetens slightly when cooked in the dish.
- Bacon
- Adds salty, smoky fat, and its rendered grease becomes the base of the dressing.
- Vinegar
- Adds acidity that cuts the richness of the bacon grease and brightens the salad.
The step that matters
Pour the dressing over the warm potato mixture and mix lightly. Potatoes absorb dressing best while still hot, so they take up flavour evenly. Mixing gently keeps the thin slices from breaking apart and turning mushy.
Swap the potato
