Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Royal Potato Salad
Ingredients
Directions
Boil the potatoes
Scrub the small potatoes well in cold water.
Place them in an earthenware or graniteware pot and cover with cold water.
Add the tied dill or caraway seed to the pot.
Boil the potatoes quickly, keeping the pot covered and reducing heat as water evaporates.
Once done, pour off the water and return the pot to the stove uncovered until all moisture steams away.
Let the potatoes cool, then peel and cut them into squares.
Make the salad
Finely chop the onion and mix it with the potatoes.
Add finely chopped parsley, a sprinkle of celery seed, and salt to taste.
Finely chop a dill pickle for every five potatoes and mix again.
Heat the oil and vinegar separately, using 1 tablespoon of oil for every 3 potatoes and 1 teaspoon of vinegar for every 4 potatoes.
Pour the hot vinegar over the salad first, then add the oil.
Flavor with lemon juice or serve with sliced lemon and grated raw beets.

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, holding their shape when boiled, peeled and cut.
- Oil
- Adds fat and richness, coating the potatoes and carrying flavor.
- Vinegar
- Adds acidity that sharpens the flavor and balances the oil.
- Onion
- Adds sharp, savory flavor and aroma to the salad.
- Dill pickle
- Adds tangy, salty crunch and acidity.
The step that matters
Dressing the warm potatoes with hot vinegar first, then oil. Potatoes absorb liquids most readily while still warm, so pouring the hot vinegar over them first lets them take up its acidity and flavor. Adding the oil afterward coats the pieces without the vinegar being blocked from soaking in.
Swap the onion
How well each one fits the dish's main ingredients (potato, dill, parsley, celery, vinegar, lemon):
- Carrotfits better
- Mustardfits better
- Broccolifits better
- Onionthe original
Fit is the average pairing score against potato, dill, parsley, celery, vinegar, lemon. Candidates are from the same food group and used in at least 100 recipes.
