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 ↓
German Potato Salad
Ingredients
Directions
Prepare
Boil the potatoes with skins on; when cold, peel and slice them onto a platter.
Fry the diced pork fat in a pan until golden brown and crisp, then remove and set aside.
Make the salad
In a bowl, gently mix the sliced potatoes with the hot pork fat, then add salt, pepper, onion, parsley, and vinegar.
Finally, add the crisp pieces of pork just before serving.
Serve the salad cold, mixing only right before you want to eat.

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 fat and vinegar dressing.
- Pork fat
- Adds rich flavour and coats the potatoes, while the crisp pieces add texture.
- Strong vinegar
- Adds acidity that brightens the rich pork fat and balances the flavour.
- Onion
- Contributes sharp, pungent aroma and a bit of bite.
The step that matters
Dress the potatoes while they are still warm. Warm potatoes are porous and absorb the hot fat and vinegar well, so flavour penetrates them. Cold potatoes stay bland on the surface. Adding the crisp pork just before serving keeps it from going soft in the dressing.
Swap the parsley
How well each one fits the dish's main ingredients (pork, vinegar, pepper, potato, onion):
- Garlicfits better
- Thymefits better
- Parsleythe original
- Dillfits about as well
Fit is the average pairing score against pork, vinegar, pepper, potato, onion. Candidates are from the same food group and used in at least 100 recipes.
