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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Provides the bulk and starch that hold the balls together and give a soft interior.
- Egg
- Binds the potato mixture so the balls keep their shape when frying.
- Flour
- Forms a dry coating that helps the outside brown and crisp in the fat.
- Lard or butter
- Conducts heat to the surface and browns the outside while adding richness.
The step that matters
Frying until golden brown. If the fat is too cool, the balls absorb grease and may fall apart. If it is too hot, the outside browns before the centre heats through. Steady medium heat cooks them evenly.
Swap the potato
How well each one fits the dish's main ingredients (egg, flour, butter):
- Chivefits better
- Shallotfits better
- Leekfits better
- Potatothe original
Fit is the average pairing score against egg, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
