Why it works: Pepper and parsley 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 potatoes
In a bowl, combine the diced potatoes with salt and pepper.
Layer the potatoes in a fancy dish, then sprinkle the sieved egg yolk and chopped parsley on top.
Make the cooked dressing
In a double boiler, mix the beaten egg yolks, mustard, salt, cayenne, sugar, melted butter or olive oil, cream or milk, and beaten egg whites.
Cook the mixture in the double boiler until slightly thickened.
Remove from heat and stir in the hot vinegar.
Finish and serve
Once cooled, pour the dressing over the potato salad.

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 absorb the dressing's flavour as it sits.
- Egg yolks
- Thicken the dressing as they cook and give it a rich, smooth body.
- Egg whites
- Add airy volume and lightness to the cooked dressing mixture.
- Cream or milk
- Adds moisture and softness, mellowing the sharpness of the vinegar.
- Vinegar
- Adds acidity that brightens the dressing and balances its richness.
- Butter or olive oil
- Adds fat for richness and a smoother mouthfeel in the dressing.
The step that matters
Cooking the dressing until slightly thickened. Egg proteins set as they heat, thickening the dressing. Overheating can scramble the eggs and leave lumps, so cook gently and stir constantly in the double boiler.
Swap the mustard
How well each one fits the dish's main ingredients (potato, pepper, egg, parsley, sugar, butter, cream):
- Chivefits better
- Capsicumfits better
- Leekfits better
- Mustardthe original
Fit is the average pairing score against potato, pepper, egg, parsley, sugar, butter, cream. Candidates are from the same food group and used in at least 100 recipes.
