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 ↓
Codfish Balls
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Combine shredded codfish and mashed potatoes.
Season with butter, pepper, and salt if needed.
Form the mixture into balls.
Coat and bake
Beat eggs and mix in milk.
Dip each ball into the egg and milk mixture.
Place the balls in a greased baking pan.
Bake in a 400°F (200°C) oven, basting frequently with the egg and milk mixture, until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shredded codfish
- Provides the main flavour and the body of the fish mixture.
- Mashed potatoes
- Binds the fish together and gives the balls a soft, moist interior.
- Eggs
- Bind the coating and help it set and turn golden in the oven.
- Milk
- Thins the egg coating so it clings evenly and adds moisture and browning.
The step that matters
Basting with the egg and milk mixture while baking. Basting keeps the coating moist so the surface can brown evenly rather than drying out or cracking. Egg proteins set as they heat, so the coating needs to stay coated over the balls throughout baking.
Swap the potato
How well each one fits the dish's main ingredients (butter, pepper, egg, milk):
- Capsicumfits about as well
- Potatothe original
- Asparagusfits about as well
- Chivefits less well
Fit is the average pairing score against butter, pepper, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
