Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. 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
- Cold cooked fish
- Forms the main body of the balls, providing the savory flavor and bulk.
- Flour
- Thickens the butter and milk into a white sauce that binds the fish together.
- Butter
- Enriches the white sauce, adding fat and a smooth, rich texture.
- Milk
- Makes the white sauce liquid, adding moisture that keeps the balls tender.
- Egg white
- Acts as a glue so the crumb coating adheres and browns evenly when fried.
The step that matters
Cool the white sauce before blending it with the fish. A hot sauce would partly cook the fish and make the mixture loose and sticky, so the balls would be hard to shape and could fall apart in the fat. Cooling it first gives a firm mixture that holds its shape.
Swap the white pepper
How well each one fits the dish's main ingredients (fish, flour, butter, milk, egg):
- Nutmegfits better
- Capersfits better
- Cinnamonfits better
- White pepperthe original
Fit is the average pairing score against fish, flour, butter, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
