Why it works: Potato and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 5,355 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Fish Balls
Ingredients
Directions
Prepare the mixture
Boil the codfish and potatoes in water until soft.
Drain the mixture, then add the dripping and beat until light and smooth.
Allow to cool slightly, then mix in the beaten eggs and salt to taste.
Add flour as needed to stiffen the mixture.
Use stock to adjust consistency.
Shape and fry
Form into balls and brown in deep fat.

The flavor team
The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Egg and flour barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Provides the main flavour and body of the fish balls.
- Raw potatoes
- Starch bulks out the mixture and helps it hold together when shaped.
- Dripping
- Adds fat that makes the mixture rich and smooth.
- Eggs
- Bind the mixture so the balls keep their shape.
- Flour
- Stiffens the mixture so it can be formed into balls.
The step that matters
Browning in deep fat. The balls must be fully heated through as well as browned on the outside. Browning happens at the surface, so frying too hot can colour them before the centre is hot, while frying too cool leaves them greasy.
Swap the potato
How well each one fits the dish's main ingredients (egg, flour):
- Arrowrootfits better
- Chivefits better
- Shallotfits better
- Potatothe original
Fit is the average pairing score against egg, flour. Candidates are from the same food group and used in at least 100 recipes.
