Why it works: Beef and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 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
- Liver
- Forms the main body of the dumplings and gives them their rich flavor.
- Eggs
- Bind the mixture and help the dumplings set when heated.
- Flour
- Adds structure so the dumplings hold their shape in the liquid.
- Breadcrumbs
- Thicken the butter and milk into a sauce with body.
- Butter
- Adds fat and richness, and browns the breadcrumbs for flavor.
- Milk
- Makes the breadcrumb mixture smooth and creamy as a sauce.
The step that matters
Drop the dumplings into boiling liquid. Eggs and flour set when heated, so the dumplings must enter boiling liquid to firm up quickly. If the liquid is not boiling, they can break apart or turn soggy.
Swap the onion
How well each one fits the dish's main ingredients (beef, egg, pepper, flour, butter, milk):
- Potatofits better
- Capsicumfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against beef, egg, pepper, flour, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
