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 ↓
German Potato Salad
Ingredients
Directions
Prepare
Boil the potatoes, then peel while hot and slice them into ⅛ inch thick pieces into a deep bowl.
Add ½ cup hot bacon or ham fat and ⅓ cup hot vinegar to the potatoes, mixing carefully.
Cover with a plate and let the mixture cool.
Finish and serve
One hour before serving, mix in the thinly shaved onion, chopped parsley, and chopped hard-cooked eggs.
Season with pepper and coarse sea salt to taste, and serve on a bed of lettuce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the body of the salad, holding their shape when sliced while hot.
- Bacon or ham fat
- Adds richness and fat that coats the potato slices and carries flavour.
- Vinegar
- Adds acidity that gives the salad its sharp, tangy flavour.
- Onion
- Adds sharp aroma and pungent bite to the salad.
- Hard-cooked eggs
- Add soft texture and mild richness to the salad.
The step that matters
Dressing the potatoes while hot. Warm potato slices absorb the hot fat and vinegar far better than cold ones, so the flavour soaks in evenly. Mixing gently keeps the slices intact rather than breaking them into mush.
