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 with Bacon
Ingredients
Directions
Prepare
Chop the hard-cooked eggs coarsely and combine with warm, seasoned potatoes.
Beat together the hot bacon fat, vinegar, mustard, onion, and parsley.
Stir the mixture into the potatoes.
Dress and serve

Garnish with strips of cooked bacon and pimento, and pour salad dressing on top.
Decorate with celery tips, watercress, celery curls, and olives if desired.

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, absorbing the warm bacon fat and dressing.
- Hard-cooked eggs
- Add body and richness, with their soft texture blending into the salad.
- Bacon fat
- Carries flavour and moisture, coating the potatoes while still hot.
- Vinegar
- Adds acidity that sharpens the flavour and balances the fat.
- Boiled salad dressing
- Binds the ingredients together and adds moisture and creaminess.
The step that matters
Add the dressing when cold. Adding the boiled salad dressing to warm potatoes can thin it and make the salad greasy or loose. Waiting until the salad is cold lets the dressing bind the ingredients and hold its texture.
Swap the onion
How well each one fits the dish's main ingredients (potato, parsley, egg, vinegar, mustard, pepper):
