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 ↓

In a bowl, combine the grated potato, flour, baking powder, and salt.
Mould the mixture into soft balls.
Drop the balls immediately into boiling salted water.

Let the onion brown, then pour the mixture over the dumplings.
Serve hot.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raw grated potato
- Adds moisture and body to the soft dough.
- Flour
- Provides the structure that holds the dumplings together.
- Baking powder
- Releases gas that helps the dumplings rise and become light.
- Butter
- Adds fat and richness, and helps the onion brown.
- Onion
- Adds sweetness and savoury flavour when it browns.
The step that matters
Drop the balls immediately into boiling salted water. Boiling water sets the outside of the dough quickly, so the dumplings hold their shape. Waiting lets the soft dough soften and break apart, and the baking powder starts releasing gas before cooking, which weakens the rise.
Swap the onion
How well each one fits the dish's main ingredients (potato, flour, egg, butter):
- Chivefits better
- Leekfits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against potato, flour, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
