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
Make the dressing
In a bowl, mix salt, pepper, parsley, onion, and salad oil or butter.
Add vinegar to the mixture and stir well.
Assemble and rest
Slice the cold boiled potatoes, ensuring the slices are not too thin.
Pour the dressing over the potatoes and let them stand for 30 minutes before serving.

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 absorb the dressing as the potatoes stand.
- Vinegar
- Adds acidity that brightens the dressing and balances the richness of the oil or butter.
- Salad oil or melted butter
- Carries the flavors of the seasonings and coats the potato slices with fat for a smooth mouthfeel.
- Grated onion
- Adds a sharp, aromatic flavor that mellows as the salad stands.
The step that matters
Slicing the potatoes. Slices that are too thin break apart and turn mushy when dressed, while thicker slices hold their shape and absorb the dressing evenly.
Swap the onion
How well each one fits the dish's main ingredients (pepper, parsley, butter, vinegar, potato):
- Capsicumfits better
- Carrotfits better
- Chivefits about as well
- Onionthe original
Fit is the average pairing score against pepper, parsley, butter, vinegar, potato. Candidates are from the same food group and used in at least 100 recipes.
