Why it works: Tarragon and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,563 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Potato Salad
Ingredients
Directions
Prepare
Boil the potatoes until just done, then drain and dry them.
In a bowl, combine salt and white pepper.
Gradually add olive oil, then mix in tarragon vinegar and sliced onion.
Make and chill the salad
Cut the hot potatoes into the mixture, tossing gently to avoid breaking them.
Set the bowl aside until the mixture is very cold.
Serve
Serve on a dish garnished with parsley, topped with sardines, and sprinkle with chopped parsley and pickled beets.

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, holding their shape when dressed and chilled.
- Olive oil
- Adds richness and carries flavour through the dressing.
- Tarragon vinegar
- Adds acidity that brightens the dressing and balances the oil.
- Onion
- Adds sharp, aromatic flavour that mellows as the salad chills.
The step that matters
Cutting the hot potatoes into the dressing. Hot potatoes absorb the oil and vinegar readily, so they take on the dressing's flavour. Tossing gently keeps the slices intact rather than breaking them into a mash.
Swap the white pepper
How well each one fits the dish's main ingredients (potato, olive, tarragon, vinegar, onion, parsley):
