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 small potatoes with jackets on the day before. Do not overcook.
The next day, peel and slice the potatoes rather thin.
Make the dressing
Fry the bacon until crispy, then add the sliced onion. Do not let it brown.
Add the vinegar to the bacon and onion mixture.
Combine and serve
Gently mix in about 1 quart of the sliced potatoes, along with a little salt and pepper.
Ensure the potatoes are well coated with the fat and look shiny.
If not sour enough, add more vinegar.
Serve hot with frankfurter sausage or redhots.

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 flavour as they are tossed.
- Bacon fat
- Carries flavour and coats the potato slices, giving them a glossy, moist texture.
- Vinegar
- Adds sharpness that balances the richness of the bacon fat.
- Onion
- Adds sweetness and aroma when softened in the bacon fat.
The step that matters
Do not let the onion brown. Browning turns the onion bitter and harsh and changes the clean, mild flavour the dressing needs. Keeping heat gentle lets the onion soften and sweeten in the fat.
Swap the potato
How well each one fits the dish's main ingredients (onion, vinegar, pepper):
- Capsicumfits better
- Mustardfits better
- Cabbagefits better
- Potatothe original
Fit is the average pairing score against onion, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
