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
Wash, peel, and cut the potatoes into quarters; soak in cold water.
Wash the codfish and break it into half-inch pieces, removing any bones.
Make the mixture
In a kettle, combine the potatoes and codfish, cover with boiling water, and cook until the potatoes are soft, about 25 minutes.
Drain all the water, then mash the mixture until very light.
Add the butter and pepper; when slightly cooled, mix in the egg and additional salt if needed.
Shape the mixture into tablespoon-sized balls.
Fry and serve
Fry in hot oil until golden brown, cooking only 4 or 5 at a time to maintain oil temperature.
The oil should be hot enough to brown a piece of raw potato in 40 seconds.
Drain on paper towels and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Provides the main flavor and savory fish character of the balls.
- Potatoes
- Mashed starch gives the balls a light, soft body and helps bind the mixture.
- Egg
- Binds the mashed mixture together so the balls hold their shape while frying.
- Butter
- Adds richness and moisture to the mashed mixture.
The step that matters
Keeping the frying oil hot. Frying only 4 or 5 balls at a time keeps the oil temperature up. If the oil cools, the balls absorb more oil, turn greasy and brown unevenly.
