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 ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Cold mashed potatoes
- Provide the bulk and starch that hold the balls together.
- Egg yolk
- Adds richness and helps bind the mixture into a cohesive dough.
- Melted butter
- Adds fat for a softer, richer texture and a light colour.
- Flour
- Forms a dry coating that helps the outside brown during frying.
The step that matters
Fry in hot lard for about 2 minutes until golden. If the lard is not hot enough, the balls absorb fat and turn greasy instead of crisping. Too hot and the outside browns before the centre heats through. Keeping the fat at a steady frying temperature gives a crisp, golden exterior.
Swap the potato
How well each one fits the dish's main ingredients (butter, egg, flour, ham):
- Shallotfits better
- Leekfits better
- Asparagusfits better
- Potatothe original
Fit is the average pairing score against butter, egg, flour, ham. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
