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 ↓

Prepare

Mix in the sliced onion, add the fried bacon and the fat from the pan, then stir in the vinegar.

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 and absorb the dressing as they cool and soften.
- Smoked bacon
- Adds savory, smoky flavor and fat that carries into the dressing.
- Vinegar
- Adds acidity that brightens the salad and balances the fat from the bacon.
- Onion
- Adds sharp, aromatic flavor that mellows slightly when mixed with the warm potatoes.
The step that matters
Slice the potatoes while they are still warm and dress them promptly. Potato starch absorbs dressing best while the slices are still slightly warm. Once cold and firm, the slices take up less seasoning and vinegar, so the salad can taste flat. Peeling and slicing after cooling is what the record states, so keep the slices thin and handle them gently to avoid breaking them.
Swap the potato
How well each one fits the dish's main ingredients (onion, pepper, vinegar):
- Capsicumfits better
