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
Cover the shredded codfish with cold water and let it stand for at least 1 hour.
Drain, cover with fresh water, and boil until tender.
Drain and remove bones from the codfish.
Make and fry the cakes
Mash several boiled potatoes and mix with the codfish.
Add a small quantity of milk, a piece of butter, and pepper to taste.
If desired, beat two eggs into the mixture before forming cakes.
Form the mixture into cakes, dip in flour, and fry until 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 savory flavor and the fish body of the cakes.
- Potatoes
- Adds starch and bulk, giving the mixture a soft, binding texture.
- Milk
- Adds moisture and softness to the mashed mixture.
- Butter
- Adds richness and fat, improving flavor and mouthfeel.
- Flour
- Dusted on the cakes, it helps them brown evenly when fried.
- Eggs
- Optional; helps bind the mixture and adds richness.
The step that matters
Remove the bones from the codfish. Small bones left after boiling can end up in the cakes and be swallowed. Picking the fish apart carefully while it is still warm makes the flakes easier to separate from the bones.
Swap the potato
