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
Prepare the dough
Mash or sieve the cooked potatoes.
Add melted butter, egg yolks, flour, dissolved Marmite, and salt; mix into a smooth paste.
Whisk the egg whites until stiff and gently fold into the potato mixture.
Shape the mixture into small balls using a little flour.
Cook and serve
Cook the dumplings in fast-boiling salted water for 15 minutes.
Drain and serve hot with tomato sauce.

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
- Cooked potatoes
- Provide the starchy bulk that holds the dumplings together.
- Eggs
- Whisked whites add lift and lightness, while yolks bind the mixture.
- Melted butter
- Adds fat for richness and a tender texture.
- Flour
- Gives the paste structure so the dumplings hold their shape in water.
- Marmite
- Adds savoury, umami depth to the dumplings.
The step that matters
Folding in the whisked egg whites. Overmixing knocks out the air in the stiffly whisked whites, leaving dense dumplings. Fold gently, just until no white streaks remain, so the mixture stays light.
Swap the potato
How well each one fits the dish's main ingredients (egg, butter, flour):
- Chivefits better
- Shallotfits better
- Leekfits better
- Potatothe original
Fit is the average pairing score against egg, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
