Why it works: Pepper and parsley 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
Cut the cold boiled potatoes into moderately thick slices.
In a bowl, combine the potatoes with vinegar, oil, salt, pepper, and minced parsley.
For added flavor, include slices of beet-root and Portugal onions.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Waxy potatoes
- Hold their shape when sliced and tossed, giving the salad its body and texture.
- Vinegar
- Adds acidity that brightens the flavor and balances the richness of the oil.
- Oil
- Coats the potato slices, adding richness and carrying the seasonings through the salad.
The step that matters
Toss gently to mix all ingredients.. Waxy potatoes hold their shape because they have less starch and stay firm when cold. Vigorous mixing breaks the slices and turns the salad mushy, so fold them carefully.

Fit is the average pairing score against potato, vinegar, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
