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
Directions
Prepare the vegetables
Boil the potatoes in their skins, then drain and peel them.
Once cold, cut the potatoes into small pieces.
Chop the lettuce, onions, parsley, and mint very finely.
Layer the potatoes and salad, seasoning each layer with pepper and salt.
Make the dressing and serve
Beat the eggs with a little milk or cream and vinegar.
Stir the mixture over low heat until it thickens.
Cool the mixture, then pour it over the salad and mix well.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken when gently heated, binding the dressing into a creamy coating.
- Vinegar
- Adds acidity that brightens the dressing and balances the richness of the eggs.
- Potatoes
- Form the bulk of the salad, absorbing the dressing while keeping their shape when cut small.
The step that matters
Stir the egg mixture over low heat until it thickens. Egg proteins set at moderate temperatures, but high heat scrambles them into lumps. Gentle, constant stirring keeps the dressing smooth.
Swap the mint
How well each one fits the dish's main ingredients (potato, lettuce, onion, parsley, pepper, egg, milk):
- Dillfits better
- Thymefits better
- Tarragonfits better
- Mintthe original
Fit is the average pairing score against potato, lettuce, onion, parsley, pepper, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
