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 ↓
Perfect Codfish Balls
Ingredients
Directions
Prepare the potatoes and fish
In a large saucepan, combine sliced potatoes and codfish.
Pour cold water over the mixture until covered, then bring to a boil.
Once boiling, pour off the water, add fresh boiling water, and cook until potatoes are done.
Drain well and mash the potatoes and fish together until fine.
Shape and fry
Add butter, black pepper, and beaten egg yolks; mix well.
If too soft, add a little cream to help form into balls.
Shape the mixture into balls or cakes.
Heat fat in a pan until thoroughly hot, then drop in the balls.
Cook until golden brown, then drain on brown paper.
Serve hot on a heated platter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Provides the salty, savory flavor and the flaky texture of the fish cakes.
- Potatoes
- Mashed starch binds the mixture and gives the balls a soft, fluffy interior.
- Butter
- Adds richness and moisture to the mashed mixture.
- Egg yolks
- Bind the mashed potato and fish so the balls hold their shape.
The step that matters
Heat the fat until thoroughly hot before adding the balls. If the fat is not hot enough, the balls absorb oil and cook slowly, becoming greasy instead of crisp and golden. Hot fat sears the outside quickly, forming a crust that holds the shape and limits oil uptake.
Swap the potato
How well each one fits the dish's main ingredients (butter, pepper, egg, cream):

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