Why it works: Butter and bread 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 ↓

Butter and flour 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 starchy body of the dough that holds the dumplings together.
- Butter
- Adds richness and fat that keeps the dough tender and flavorful.
- Egg yolks
- Bind the dough and add richness and structure as they set.
- Sour cream
- Adds moisture and a slight tang that keeps the dough soft.
- Flour
- Absorbs moisture and gives the dough enough structure to roll and shape.
The step that matters
Kneading in the flour. Adding too much flour or overworking the dough makes dumplings dense and tough, because starch and gluten build up. Knead only until the dough comes together.

- Plumthe original
Fit is the average pairing score against potato, butter, egg, cream, flour, bread. Candidates are from the same food group and used in at least 100 recipes.
