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 ↓

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, with a tender body that holds its slices when mixed gently.
- Bacon
- Adds savory, browned flavor and fat that carries flavor through the salad.
- Mayonnaise
- Adds fat and creaminess that coats the potatoes and binds the salad together.
- Vinegar
- Adds acidity that brightens the flavor and cuts the richness of the bacon and mayonnaise.
- Onion
- Adds sharp, pungent flavor that contrasts with the potatoes and bacon.
The step that matters
Mix carefully to avoid breaking the potatoes.. Potato slices are fragile once cooked and cut, and rough stirring breaks them into mush. Gentle folding keeps the slices intact and gives the salad an appealing texture.
Swap the onion
How well each one fits the dish's main ingredients (potato, parsley, vinegar, pepper):
- Carrotfits better
- Capsicumfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against potato, parsley, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
