Why it works: Milk and butter 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
Prepare the codfish
Soak the codfish overnight in cold water.
In the morning, place the fish in fresh water and heat until scalding hot but not boiling.
Remove bones and mash the fish finely.
Make the mixture
Combine the fish with the hot, sifted potatoes, egg, milk or cream, butter, salt, and pepper.
Beat the mixture until very light.
Fry and serve
Form into flat cakes, coat with flour, and fry in hot lard until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Provides the main flavor and body of the cakes.
- Potatoes
- Add starch and bulk so the mixture holds together and stays soft inside.
- Egg
- Binds the mixture so the cakes hold their shape while frying.
- Milk or cream
- Adds moisture and softness to the mixture.
- Butter
- Adds fat for richness and a tender texture.
The step that matters
Beat the mixture until very light. Beating incorporates air and works the potato starch, which lightens the texture of the mixture. Thorough beating helps the cakes stay tender rather than dense.
Swap the potato
How well each one fits the dish's main ingredients (egg, milk, butter, pepper, flour):
- Capsicumfits about as well
- Potatothe original
- Asparagusfits about as well
- Chivefits about as well
Fit is the average pairing score against egg, milk, butter, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
