Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Codfish Balls
Ingredients
Directions
Prepare the mixture
Boil codfish and potatoes in plenty of cold water until the potatoes are thoroughly cooked.
Drain off all the water and mash the mixture with a potato masher.
Add butter, egg, and cream or milk to the mashed mixture and mix well.
Shape and fry
Flour your hands and shape the mixture into balls or cakes.
Heat butter and lard in a frying pan until hot.
Fry the balls until they are a nice brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Provides the main savoury flavour and body of the balls.
- Potatoes
- Bind the fish together and give the mixture a soft, mashable texture.
- Egg
- Binds the mixture so the balls hold their shape while frying.
- Cream or rich milk
- Adds moisture and richness to keep the mashed mixture tender.
- Butter
- Adds richness to the mixture and helps the outside brown in the pan.
The step that matters
Frying the balls until nicely brown. The balls are already cooked, so the frying is about browning the surface. Frying in hot fat browns the outside through the Maillard reaction while keeping the inside tender, so the pan must be hot before the balls go in.

Fit is the average pairing score against butter, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
