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
Wash and boil the potatoes without peeling them.
Once cooked, let them cool, then peel and cut into slices or cubes.
While the potatoes are still hot, pour the dressing over them.
To make the dressing, mix cream, oil, vinegar, cayenne, salt, onion, and parsley.

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, providing starchy body and structure once cut.
- Cream
- Adds richness and a creamy coating that softens the dressing's sharpness.
- Oil
- Carries fat into the dressing, giving smooth mouthfeel and helping flavours coat the potatoes.
- Tarragon or cider vinegar
- Adds acidity that brightens the dressing and balances the cream and oil.
The step that matters
Dressing the potatoes while they are still hot. Warm potato starch is softer and more porous, so it absorbs the dressing well. Once cold, the surfaces firm up and the dressing sits on top instead of soaking in.
Swap the onion
How well each one fits the dish's main ingredients (potato, cream, tarragon, pepper, parsley):
- Chivefits better
- Carrotfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against potato, cream, tarragon, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
