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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the balls and gives them their savoury flavour.
- Mashed potatoes
- Adds starch and body so the mixture holds together when shaped.
- Butter
- Adds richness and helps the outside of the balls brown when fried.
- Milk
- Adds moisture so the fish and potato mixture is soft enough to shape.
- Egg
- Binds the mixture so the balls hold their shape while frying.
The step that matters
Fry the balls in butter on both sides until light brown. Cooking over moderate heat until the surface is light brown sets the outside and gives flavour through browning. Too much heat can scorch the butter and leave the centre underdone, so turn the balls gently.
Swap the potato
How well each one fits the dish's main ingredients (fish, butter, milk, egg, pepper):
- Potatothe original
- Capsicumfits about as well
- Asparagusfits less well
- Chivefits less well
Fit is the average pairing score against fish, butter, milk, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
