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 Salad
Ingredients
Directions
Prepare
Boil the potatoes until they are soft enough to stick a fork in, then drain and let them cool uncovered for 15 minutes.
Slice the onion very finely.
Cut the bacon into small dice and fry until crisp and brown.
Assemble the salad
Once the potatoes are cool, peel and slice them thinly, then season with salt and pepper.
Mix in the sliced onion, fried bacon, and the fat from the pan. Add the vinegar and toss to combine.
Garnish with green salad.

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 while absorbing the dressing.
- Smoked bacon
- Adds smoky, salty flavour and rendered fat that carries flavour through the salad.
- Onion
- Adds sharp, pungent flavour and crunch when sliced very finely.
- Vinegar
- Adds acidity that brightens the salad and balances the richness of the bacon fat.
The step that matters
Slice the potatoes while they are still cool. Cooled cooked potatoes hold their shape when sliced thinly, while warm ones tend to crumble or turn mushy. Boiling until just soft, then cooling, helps the slices stay intact and absorb the dressing evenly.
Swap the potato
How well each one fits the dish's main ingredients (onion, pepper, vinegar):
- Capsicumfits better
- Mustardfits better
- Cabbagefits better
- Potatothe original
Fit is the average pairing score against onion, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
