Why it works: Cream and butter 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
Wash and pick over the salt fish, shredding it into small pieces.
Peel the potatoes and cut them into quarters.
Make the mixture
Put the fish and potatoes in a saucepan, cover with boiling water, and cook for 25 minutes or until the potatoes are tender.
Drain thoroughly, then mash and beat the mixture with a fork until light.
Add the melted butter and mix, then cool slightly.
Beat the egg and add it to the mixture along with the cream, adding gradually until the mixture is not too soft.
Shape and fry
Form the mixture into balls, cover with egg and bread crumbs, and fry in hot oil.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt fish
- Provides the main savory flavor and salty character of the balls.
- Potatoes
- Provide starch and bulk that hold the mixture together and keep it tender.
- Egg
- Binds the mixture so it holds its shape during frying.
- Melted butter
- Adds fat for richness and a softer, more tender texture.
- Cream
- Adds moisture and softness to the mixture.
The step that matters
Adding the egg and cream gradually. Too much liquid makes the mixture soft and sticky, so the balls may fall apart in the hot oil. Adding the liquid a little at a time lets you stop once the mixture is firm enough to shape.
Swap the potato
How well each one fits the dish's main ingredients (cream, egg, fish, butter, pepper):

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