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 ↓
Fish Cakes
Ingredients
Directions
Prepare the mixture
Remove bones from the codfish and mince the meat.
Combine the minced fish with warm mashed potatoes, using two-thirds the amount of fish.
Add a little butter, beaten eggs, and milk to create a smooth paste.
Season the mixture with pepper.
Shape and fry
Form the mixture into cakes about 1 inch thick.
Sprinkle the cakes with flour.
Fry the cakes in butter until they are brown.

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
- Codfish
- Provides the main body and flavour of the cakes.
- Mashed potatoes
- Adds bulk and moisture, helping the cakes hold together.
- Beaten eggs
- Bind the mixture so it holds its shape when fried.
- Flour
- Dries the surface so the cakes brown well in the butter.
The step that matters
Frying the cakes in butter until brown. Frying over steady heat browns the outside through the Maillard reaction while the inside heats through. Too little heat leaves them pale and soggy, and too much burns the flour coating before the centre is hot.
Swap the potato
How well each one fits the dish's main ingredients (fish, butter, egg, milk, pepper, flour):

Fit is the average pairing score against fish, butter, egg, milk, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
