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 ↓
Potato Salad
Ingredients

Prepare
Boil the potatoes in their skins, then peel and slice them while hot.
Cut the bacon into small dice and fry until nicely browned.
Drain the bacon well from fat and combine it in a bowl with the sliced potatoes and onion.

Add the mayonnaise and mix gently.

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 hold their shape when sliced while hot.
- Bacon
- Adds savory, browned fat flavor and crisp bits to the salad.
- Mayonnaise
- Adds creaminess and moisture that binds the salad together.
- Vinegar
- Adds acidity that brightens the flavor and balances the richness of the bacon and mayonnaise.
The step that matters
Drain the bacon well from fat. Excess bacon fat left in the bowl will make the salad greasy and can coat the potatoes unevenly, so drain thoroughly before combining.
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.
