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 Balls
Ingredients
Directions
Prepare
Break the cold fish into pieces with a fork, removing all bones and skin, and shred it very fine.
Add an equal quantity of mashed potatoes to the fish.
Make a stiff batter by mixing in butter, milk, and the beaten egg.
Shape and fry
Flour your hands and shape the mixture into balls.
Fry the balls in boiling lard or drippings until they are light brown.

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 fish
- Provides the main body and flavor of the balls.
- Mashed potatoes
- Adds bulk and softness, helping the mixture hold together.
- Butter
- Adds richness and moisture to the batter.
- Milk
- Moistens the batter so it binds smoothly.
- Egg
- Binds the mixture so the balls hold their shape while frying.
The step that matters
Fry in boiling fat. The fat must be hot enough to brown the outside quickly. If it is too cool, the balls absorb grease and turn heavy and soggy before they set.
Swap the potato
How well each one fits the dish's main ingredients (fish, whitefish, turbot, butter, milk, egg, flour):

- Leekfits about as well
Fit is the average pairing score against fish, whitefish, turbot, butter, milk, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
