Why it works: Egg and bread are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 22,662 recipes. Both carry (e)-2-octenal, which smells fatty, green. The science ↓
German Potato Dumplings
Ingredients
Directions
Prepare the dough
Grate the raw potatoes, drain off all the water, and squeeze them in a cloth.
Add the cold boiled potatoes, also grated, and mix with the other ingredients.
Form the mixture into balls the size of a goose egg.
Cook and serve
Put the balls into boiling water and boil for half an hour or until they rise to the top.
Fry a chopped onion in butter until brown, then add 2 cups of water to make a sour sauce.
Serve the dumplings with meat gravy, butter, or the sour sauce.

Egg and flour barely smell alike, yet cooks put them together in 106,462 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 potatoes
- Provide starch and bulk that give the dumplings their body and chew.
- Cold boiled potatoes
- Add moisture and a softer texture to the grated raw potato mixture.
- Eggs
- Bind the mixture so the dumplings hold together while cooking.
- Flour
- Absorbs moisture and gives the dough structure so it keeps its shape.
- Baking powder
- Releases gas that lightens the dumplings and helps them rise.
- Bread
- Adds fried, diced pieces that give texture and a toasted flavour.
The step that matters
Squeeze the raw potatoes dry. Raw grated potato holds a lot of water. If it is not drained and squeezed well, the excess liquid makes the dough loose, so the dumplings can fall apart in the boiling water.
Swap the potato
How well each one fits the dish's main ingredients (egg, flour, bread):
- Shallotfits better
- Arrowrootfits better
- Leekfits better
- Potatothe original
Fit is the average pairing score against egg, flour, bread. Candidates are from the same food group and used in at least 100 recipes.
