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
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the fish
Remove all bones from the soaked and boiled codfish and shred it.
Let the shredded fish drain.
Mix and shape
In a bowl, combine the fish, mashed potatoes, pepper, salt, sweet milk, and the egg.
Mix well and form the mixture into rolls.
Bake
Bake in a preheated oven at 400°F (200°C) until light brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Provides the main savory flavor and the flaked body of the dish.
- Irish potatoes
- Add starch and bulk, giving the mixture a soft, cohesive texture.
- Egg
- Binds the mixture so the rolls hold their shape while baking.
- Sweet milk
- Adds moisture, keeping the mixture tender rather than dry.
The step that matters
Draining the shredded fish. Excess water in the fish would make the mixture loose and wet, so the rolls may not hold their shape or brown well. Letting the fish drain before mixing helps the rolls set firmly in the oven.
Swap the potato
How well each one fits the dish's main ingredients (pepper, milk, egg):
- Capsicumfits better
- Potatothe original
- Asparagusfits about as well
- Spinachfits about as well
Fit is the average pairing score against pepper, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
