Why it works: Flour and butter 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 ↓

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
- Egg yolks
- Bind the batter and help it set and turn golden when fried.
- Flour or grated bread
- Thickens the batter so it coats the potato slices.
- Brandy
- Adds a light aroma to the batter.
- Butter
- Fries the coated slices, adding richness and browning.
The step that matters
Frying the battered slices. The batter must be thick enough to coat the potatoes; if the butter is too hot the coating browns before the potato cooks through, and if too cool the batter absorbs fat and turns greasy.
Swap the potato
How well each one fits the dish's main ingredients (egg, brandy, flour, butter):
- Shallotfits better
- Chivefits better
- Arrowrootfits better
- Potatothe original
Fit is the average pairing score against egg, brandy, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
