Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Potatoes
- Form the bulk of the dumplings and give them a soft, starchy body.
- Egg yolks
- Add richness and bind the grated potato into a cohesive dough.
- Egg whites
- Fold in air to lighten the dough and help it hold a softer texture.
- Flour
- Absorbs moisture and helps the dough hold its shape when cooked.
- White bread
- Adds body and a toasted, buttery flavor when browned and cooled into the dough.
The step that matters
Testing a small dumpling before cooking the rest. The dough's moisture and binding vary with the potatoes, so a test dumpling shows whether it will hold together in boiling water. If it breaks apart, the extra egg or flour adjustment prevents the whole batch from falling apart while cooking.
