Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Potato Dumplings
Ingredients
Directions
Make the dough
Mash the potatoes while warm.
Add the butter, salt, sugar, and a pinch of mace or nutmeg.
Beat the egg yolks and whites separately, then mix with the potato mixture.
Add enough flour to make a stiff batter.
Cook the dumplings
Drop ½ teaspoon of the batter at a time into boiling soup and cook for 5 minutes.

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
- Provide the starchy base that gives the dumplings their body and soft interior.
- Eggs
- Bind the mixture and add structure so the dumplings hold together while cooking.
- Flour
- Thickens the mixture into a stiff batter that holds its shape in the boiling soup.
- Butter
- Adds fat for richness and a softer, more tender texture.
The step that matters
Adding the flour. Enough flour must be added to make a stiff batter. Too little leaves the dumplings loose and likely to fall apart in the boiling soup, while the starch in the flour helps them set as they cook.
Swap the mace
How well each one fits the dish's main ingredients (potato, butter, sugar, egg, flour):
- Nutmegfits better
- Cinnamonfits better
- Capersfits better
- Macethe original
Fit is the average pairing score against potato, butter, sugar, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
