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 ↓

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 dumpling and give it a soft, starchy body.
- Eggs
- Bind the mixture and help hold the dumplings together as they cook.
- Flour
- Adds body to the dough so it holds its shape when boiled.
- Onion
- Adds savory flavor and aroma once browned in fat.
- Fat
- Carries the onion's flavor and adds richness to the dough.
The step that matters
Shape the mixture into dumplings and boil in salted water for 10 minutes.. If the dough is too wet or too loose, the dumplings can break apart in the water. Enough flour gives a stiff dough that holds its shape, and keeping the water at a gentle boil helps them cook through without falling apart.
Swap the onion
How well each one fits the dish's main ingredients (potato, egg, flour, pepper):
- Chivefits better
- Spinachfits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against potato, egg, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
