Why it works: Potato and wheat match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 235 recipes. Both carry (e,z)-2,6-nonadienal, which smells cucumber, melon. The science ↓
Codfish Balls
Ingredients
Directions
Prepare the codfish
Soak the codfish overnight.
In the morning, place the codfish in a pot with enough cold water to cover it and boil until it falls apart.
Remove the codfish and shred it into very small pieces.
Make the balls
Boil the potatoes, then drain and mash them.
Add the butter, cream, and pepper to the mashed potatoes.
Mix in the shredded codfish.
Form the mixture into balls.
Roll the shredded wheat on a pastry board and coat the balls in it.
Drop the balls into boiling lard and fry until brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Forms the main body of the balls, giving them savory flavor and a flaky texture.
- Potatoes
- Mashed starch that binds the fish and gives the balls a soft, tender interior.
- Butter
- Adds fat and richness, contributing flavor and a smoother mouthfeel to the mash.
- Cream
- Adds moisture and richness, keeping the mashed potato soft and easy to shape.
- Shredded wheat biscuit
- Crushed into a crumb coating that browns during frying to give a crisp exterior.
The step that matters
Drop the balls into boiling lard and fry until brown.. The lard must be hot enough to brown the crumb coating quickly. If it is too cool, the balls absorb more fat and turn greasy and soggy before the outside crisps.

- Asparagusfits less well
Fit is the average pairing score against cream, butter, wheat, biscuit, pepper. Candidates are from the same food group and used in at least 100 recipes.
