Why it works: Potato and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 8,305 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Codfish Balls
Ingredients
Directions
Prepare the cod
Soak the salt cod in cold water for 30 minutes, then drain.
Cover the cod with boiling water and let it stand on the back of the range for 15 minutes.
Drain again and press out all excess water.
Shape and fry
Mix the cod with the well-beaten mashed potatoes and add the cream, pepper, and batter.
Beat the mixture well and form it into balls.
Roll the balls in egg and breadcrumbs (or in egg and flour) and fry in boiling lard until well browned.

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.

Shared aroma: acetic acid (sour, vinegar).
Cream and pepper barely smell alike, yet cooks put them together in 21,449 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
- Salt cod
- Provides the main savoury fish flavour and the flaky body of the balls.
- Mashed potatoes
- Bind the fish together and give the balls a soft, tender interior.
- Cream
- Adds moisture and richness so the mixture stays soft rather than dry.
- Batter
- Helps hold the mixture together and adds body to the balls.
The step that matters
Press out all excess water from the cod. Any water left in the cod dilutes the mixture and makes the balls loose and soggy, so they may break apart or fry unevenly in the hot lard.
Swap the potato
How well each one fits the dish's main ingredients (cream, pepper):
- Spinachfits better
- Capsicumfits about as well
- Potatothe original
- Horseradishfits less well
Fit is the average pairing score against cream, pepper. Candidates are from the same food group and used in at least 100 recipes.
