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 ↓

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
- Oyster plant
- Forms the bulk of the mixture, giving the balls their body and mild flavour.
- Butter
- Adds richness and fat, and browns during frying for flavour and colour.
- Egg yolk
- Binds the mashed mixture so the spoonfuls hold their shape.
- Flour
- Coats the balls, helping them brown and form a crisp outer crust when fried.
The step that matters
Fry until golden brown. The flour coating and butter brown through the Maillard reaction, which creates flavour and colour. Frying too gently leaves the balls pale and soft, while heat that is too high can scorch the butter before the centre warms through.
Swap the mace
How well each one fits the dish's main ingredients (oyster, butter, egg, pepper, flour):
- Parsleyfits better
- Nutmegfits better
- Capersfits better
- Macethe original
Fit is the average pairing score against oyster, butter, egg, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
