Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Potato Salad
Ingredients
Directions
Prepare the potatoes
Boil the potatoes until tender, then let them cool.
Remove the skin and slice the potatoes into ¼ inch thick slices.
Assemble and dress
In a salad bowl, layer the potato slices, sprinkling with a little salt, parsley, onion, and chives.
Repeat the layers until all ingredients are used, finishing with chopped greens on top.
In a separate bowl, whisk together vinegar, olive oil, salt, black pepper, and sugar.
Pour the dressing over the salad and serve.

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 and hold their shape when boiled until tender.
- Vinegar
- Adds the sharp acidity that brightens the dressing and balances the oil.
- Olive oil
- Carries flavour and gives the dressing a smooth, rich body.
- Onion
- Adds sharp, pungent flavour that mellows somewhat with the dressing.
- Sugar
- Adds a touch of sweetness that rounds out the acidity of the vinegar.
The step that matters
Let the potatoes cool before slicing and layering. Warm potatoes are fragile and can break apart when sliced, and they absorb dressing unevenly. Letting them cool to a comfortable temperature keeps slices intact and lets them take in the dressing well.
Swap the onion
