Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
German Potato Salad
Ingredients
Directions
Prepare the potatoes
Boil the potatoes in their jackets until done.
Let them cool slightly, then slice them.
Dress the salad
Add sliced onions to taste, along with pepper, coarse sea salt, vinegar, and salad oil or roast beef drippings.
Ensure the potatoes are warm and use just enough vinegar to moisten them.
Chop winter lettuce and mix it with the onions for added flavor.
Garnish the salad with the chopped lettuce for an attractive presentation.

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 and absorb the dressing while warm.
- Onions
- Add sharp, pungent flavor that mellows with the vinegar and fat.
- Vinegar
- Adds acidity that brightens the salad and moistens the potatoes.
- Salad oil or roast beef drippings
- Adds fat and richness, carrying flavor and softening the dressing's sharpness.
The step that matters
Dress the potatoes while warm. Warm potatoes open their starch structure and absorb vinegar and fat readily, so dressing them while warm gives even flavor. Cold potatoes stay firm and repel the dressing, and too much vinegar makes the salad soggy and sour.
Swap the lettuce
The recipe marks lettuce as optional. How well each one fits the dish's main ingredients (potato, onion, pepper, vinegar, beef):
- Capsicumfits better
- Chivefits better
- Tomatofits better
- Lettucethe original
Fit is the average pairing score against potato, onion, pepper, vinegar, beef. Candidates are from the same food group and used in at least 100 recipes.
